How bright can an star bright?
The brightest stars are a few million times as bright as our Sun.
Are there more stars in the sky or grains of sand on the beach?
Scientists say there are 10 times more stars in the night sky than grains of sand in the world's deserts and beaches. Astronomers have worked out that there are 70 thousand million million million - or seven followed by 22 zeros - stars visible from the Earth through telescopes!
What are the size of the stars?
For example, our Sun has a diameter of about 1.4 million kilometers. Some other stars are bigger - up to hundreds of times bigger. The majority of stars, however, are smaller than our Sun.
The largest stars are times the mass of the sun?
The largest star known, Eta Carinae, has about 150 times the Sun's mass but it is only 3 million years old and likely to explode in less than a million years so is unstable and short-lived compared to other stars.
What is the brighter than stars?
There are many stars that are brighter than the sun. Deneb shines the brightest in the constellation Cygnus and is much farther from Earth than most of the other stars you see. Deneb is about 100,000 times brighter than the Sun. HR 5171, has a diameter 1,300 times the sun and is a million times brighter than the sun. R136a1 weighs up to 300 times the mass of the Sun and is close to 10 million times brighter than the sun.
What is a normal star's diameter?
There are huge variations in a star's diameter. Our Sun has a diameter of about 1.4 million kilometers, but a few stars have hundreds of times this diameter - and of course, some stars are smaller than our Sun. It is hard to say what is "normal" with such huge variations, but probably the majority of stars are a little smaller than our Sun.There are huge variations in a star's diameter.

How big is a hyper-giant star?
Hypergiant simply means the largest of the large stars; there is no exact definition as to its size. For comparison, the largest stars (in diameter) have diameters 1000-2000 times that of the Sun; the most massive stars have 150-200 times the mass of the Sun; and the brightest stars (in absolute terms, not as seen by us) are estimated to have about 5 million times the brightness of the Sun.
Where does the earths atmosphere stop?
If you travel some 12. 5 miles into the sky, you will leave roughly 99 percent of the atmosphere behind. At 30 miles up, the density of the atmosphere is roughly one million times less than at the surface.
Do stars burn up in your atmosphere?
Because even the smallest of stars are >1000 times bigger than the Earth, stars would not burn up in our atmosphere, but instead just annihilate everything in it's path, but there's no need to worry the closest star is16.308 light-years from the Solar System, and the universe is actually expanding so no stars are going to annihilate the earth.
How big is a star compared to the earth?
Stars are significantly larger than Earth. For example, the Sun's diameter is about 109 times that of Earth. Larger stars, such as Betelgeuse, can be hundreds or even thousands of times larger than the Sun.
Is it normal for the stars to be closer to the moon?
Closer than what ?? The sun is 390 times farther from the moon than we are,and the next nearest star is about 109 million times farther from the moon thanwe are.
What could be at the center of Milky Way?
Lots of stars, dust, and gas - and a supermassive black hole, estimated to have 4 million times the mass of our Sun.
