How far apart are the stars of Leo the lion?
Thinks of a constellation as being, basically, a direction in space - the stars are not related one to another. So, some of the stars in that direction are billions of light-years away from us, and of course, billions of light-years away from the nearer stars.
Does it sometimes take millions of years for starlight to reach earth?
Not for the stars you can see without a telescope. All of the stars you see at night are within a few hundred light years of Earth, so it does not take the light more than a few hundred years to reach us. There are stars in other galaxies that are millions or even billions of light years away. That light does take millions to billions of years to reach us, though the stars are too far away for us to thee them individually.
Is betelgeuse the farthest star from earth?
Betelgeuse is not the farthest star from Earth. It is a red supergiant star located in the constellation of Orion, approximately 642.5 light years away from us. There are other stars much farther away from Earth in our galaxy.
What is the distance of the stars you see at night?
If you mean, with the naked eye: anywhere between 4 light-years, and thousands of light-years; however, there are three galaxies you can see with the naked eye, two of which are about 180,000 light-years away, while the Andromeda Galaxy is 2-3 million light-years away. With powerful telescopes, on the other hand, stars and galaxies can be seen that are millions, and even billions, of light-years away.
How far is a star?
Every star is a different distance from us. The nearest one is about 93 million miles. (That's the one called the "Sun".) The next nearest one is 4.3 light years from us. That's about 25,278,030,000,000 miles. (You can see why it's easier to use light-years than miles.) From there, there are billions and billions of stars, grouped in billions and billions of galaxies. The farthest ones we can see are about 14 billion light years away, but we're sure there are more that are farther away than that.
Why do scientist see the galaxies if they were millions and billions of years ago?
The galaxies beyond our own are millions to billions of light years away, meaning the light takes millions to billions of years to get here.
Is it possible that astronomers are discovering stars that no longer exists?
Likely only stars in other galaxies or ones that are already dying. Our galaxy is about 100,000 light years across, meaning it takes light from stars at one end 100,000 years to reach the other, which is a short time in the life of a star; most stars last billions of years while the most massive may last a few million. Other galaxies are millions to billions of light years away.
How far away are you from the Sun?
Same distance as you are. Billions of light years away.
How far away are stars and galaxies?
Stars within our own galaxy, the Milky Way, typically range from a few light-years to several thousand light-years away. For instance, Proxima Centauri, the closest star, is about 4.24 light-years away. Galaxies are much farther, with the nearest galaxy, Andromeda, located about 2.5 million light-years from Earth, while many others are billions of light-years away. The vast distances highlight the immense scale of the universe.
Why can you still see stars after they have died?
The nearest star (other than the Sun) is 4.7 light-years from Earth, meaning it takes 4.7 years for light from that star to reach us. That star could die and we would not know it for 4.7 years. Some stars are billions of light years away, it would be billions of years before we noticed that the star was no longer shining.
How far is it into space?
Billions and billions of light years away... or right in front of you. 'Tis a question for the UNIVERSE to answer, man!
Are all stars the same distance from the earth?
No two planets within our solar system have the same exact size. However, Earth and Venus are quite close - their diameters differ by only 652km.
