What was the first star named?
The oldest star yet discovered, HD 140283, nicknamed Methuselah star, is an estimated 14.46 ± 0.8 billion years old. (Due to the uncertainty in the value, this age for the star does not conflict with the age of the universe, determined by the Planck satellite as 13.799 ± 0.021).
A star is any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources.
Stars are celestial objects that can produce their own light. They are extremely hot and extremely large. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star; the sun's energy and light play one of the key roles in sustaining all forms of life on earth.
Stars are named for the constellation that they lie in with the brightest star in a constellation being alpha and so on throught the greek alphabet.

The closest star to Earth is a triple-star system called Alpha Centauri. The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are about 4.35 light-years from Earth, according to NASA (opens in new tab).
After the star's outer layer has escaped, the much smaller inner layer collapses into a white dwarf. This star, which is hotter and brighter than the red giant it came from, illuminates and warms the escaped gas, until the gas starts glowing by itself – and we see a planetary nebula.
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
The ⭐ (star) emoji represents stars, star power, and appreciation. The traditional ⭐ emoji is pretty broad, and can mean different things depending on the context of the conversation. Some people use ⭐ to represent literal stars, while other people use them to represent talent and star power.
The star which is the formation of hot gasses, energy, light and heat, which doesn't refer to the moon's qualities. So the moon is not a planet or a star.

STAR DEFINITION. A star is an exploding ball of burning gas held together by gravity. Our sun is a star! It produces great amounts of energy in the form of light and heat that provide the perfect conditions for life on Earth.

A time just after the Big Bang. Astronomers have now calculated the time when the first stars began shining. Known as cosmic dawn, the event occurred nearly 250 to 350 million years after the Big Bang and astronomers have calculated that they will be able to see the birth of these first stars as early as next year.

Background. Of the roughly 10,000 stars visible to the naked eye, only a few hundred have been given proper names in the history of astronomy. Traditional astronomy tends to group stars into constellations or asterisms and give proper names to those, not to individual stars.
Astronomers at Nasa and the European Space Agency have just discovered the youngest ever neutron star of its kind. Called Swift J1818.
A white dwarf is what remains of a star like our Sun after it sheds its outer layers and stops burning fuel though nuclear fusion.
Johann Bayer was the first to use Greek letters for star names — and four centuries later, we use them still. Here is the constellation Taurus from Bayer's Uranometria atlas of 1603. At least beginners aren't alone in their confusion of star names.
The first stars are known as Population III stars, and none have ever been observed, as they are too faint. The first stars had to make do with what they had available, and formed from clouds containing only hydrogen and helium.
What is usually the first star?
Venus shines so brightly that it is the first “star” to appear in the sky after the Sun sets, or the last to disappear before the Sun rises. Its orbital position changes, thus causing it to appear at different times of the night throughout the year.
Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.
When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant. This may be millions of kilometres across - big enough to swallow the planets Mercury and Venus. After puffing off its outer layers, the star collapses to form a very dense white dwarf.
The stars seem to twinkle in the night sky due to the effects of the Earth's atmosphere. When starlight enters the atmosphere, it is affected by winds in the atmosphere and areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.
Like people, stars are born, they grow old and they die. Their birth places are huge, cold clouds of gas and dust, known as 'nebulas'. The most famous of these is the Orion nebula, which is just visible with the unaided eye. These clouds start to shrink under their own gravity.

What if we had no moon?
Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
Distance Information
Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away.
Although the moon is our only permanent natural satellite, astronomers have discovered many other near-Earth objects that could be considered honorary 'mini' moons.
Proper Motion
Stars do move on their own, too! They're orbiting around the center of their galaxies just like Earth orbits around the Sun. This is called proper motion. Space is so huge and the stars are so far away that it doesn't look to us as if they're moving at all, but they are.
The Earth is an example of a planet and orbits the sun, which is a star. A star is usually defined as a body of gas which is large enough and dense enough that the heat and crushing pressure at its center produces nuclear fusion.
The answer is an absolutely astounding number. There are approximately 200 billion trillion stars in the universe. Or, to put it another way, 200 sextillion.
The Magnetar is a widely accepted variation on a neutron star, and a common explanation for certain phenomena (like soft gamma repeaters and anomalous X-ray pulsars). The magnetar is, at the moment, the most powerful magnetic object known to exist.
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores.
The Star of Bethlehem, or Christmas Star, appears in the nativity story of the Gospel of Matthew chapter 2 where "wise men from the East" (Magi) are inspired by the star to travel to Jerusalem.
What is it called when a star is born?
The first stage in the birth of a star is called a protostar. This is where the majority of the stellar material has collected together in ball in the center, but there is a huge disk of gas and dust obscuring it from our view. As long as there is still inflowing material, the object is a protostar.
They formed in small protogalaxies that evolved from density fluctuations in the early universe. and helium, the physics of star formation favored the creation of bodies that were many times more massive and luminous than the sun. stars exploded as supernovae, dispersing heavy elements throughout the universe.
The story of the Star of Bethlehem appears only in the Book of Matthew. The gospel tells us that a bright star appeared in the eastern sky when Jesus was born, famously seen by a group of wise men. These biblical "Magi," sometimes called kings, now adorn nativity scenes around the world.
Those first stars are thought to have been formed from existing materials a few hundred million years after the Big Bang, and they died in explosions (supernovae) after only a few million years.
So, before the Sun, there must have existed a star - probably an intermediate mass star - which evolved to become a giant, made barium in its interior, then lost its envelope through a massive wind into the interstellar medium, and that material was incorporated into the protosun.
Wormwood (ἀψίνθιον apsinthion or ἄψινθος apsinthos in Greek) is a star or angel which appears in the Book of Revelation.
The twelve stars above her head apply to both the twelve patriarchs of the tribes of Israel (original people of God), and the twelve apostles (renewed people of God). Of course, this symbolism has been interpreted in different and more subjective ways, especially for various devotional forms.
4.1. Star, Planet The Hebrew word for star is (kokhav), while planet is referred to as a 'walking star' – Curiously, Arabic uses the same root to refer to planet – (kawkab), while the word for star is (najm) or (najma).
The first stars formed when the universe was less than 2% its current age. Astronomers have detected a 13.3-billion-year-old oxygen signal, which suggests the first stars began forming just 250 million years after the Big Bang.
The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It's about 93 million miles (150 million kilometers) from Earth and it's our solar system's only star.
What was before the stars?
Until around a few hundred million years or so after the Big Bang, the universe was a very dark place. There were no stars, and there were no galaxies. After the Big Bang, the universe was like a hot soup of particles (i.e. protons, neutrons, and electrons).

Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
Galileo Galilei, an Italian scientist, lived from 1564 to 1642. In 1610, he was the first person we know of to use the newly invented telescope to look at the stars and planets.
