How far apart are stars in a constellation?
The stars in a constellation appear close together in our night sky. But they are not at all close together out in space. In the constellation Orion, the stars visible to the naked eye are at distances ranging from just 26 light-years (which is relatively close to Earth) to several thousand light-years away.
Are the constellations the same everywhere?
Like the Sun and the planets, the zodiac constellations all lie in the ecliptic, so they’re visible from every place on Earth where you can see the sun rise and set. This explains why they feature so prominently in ancient cultures. The zodiac constellations span the entire sky, so we never face all 12 of them at once.
Does everyone in the United States see the same stars?
No, the sky we see is not the same. As the earth rotates, the part of the sky that you can see will change – unless you are exactly on the North or South Poles, in which case the sky will appear to rotate around a point directly above your head so you don’t get to see any new stars as time goes on.
How do we know how far stars are away from us?
Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star’s apparent movement against the background of more distant stars as Earth revolves around the sun.
Are constellations the same distance from the sun?
Any star visible to the unaided eye can be anywhere from a few to a few thousand light years distant. The constellations are indeed very well where they are: extending far into the reaches of the starry night sky. Enjoy their distant light!…How Far are the Constellations?

Are stars in a constellation close together?
Although the stars in a constellation appear close together as we see them in our night sky, they are not at all close together out in space.
Can you see the same stars from anywhere in the world?
Are all the constellation visible from anywhere on earth in the entire year?
Answer: There are no constellations visible all-year from the Earth’s equator. By the same token, all constellations are visible at some point during a given year.
