Why would 2 stars appear different in our night sky?
In six months, after Earth moves from one side of its orbit around the Sun to the other side, the astronomer looks at the star again. This time parallax causes the star to appear in a different position relative to more distant stars.
Can you see the same stars in the northern and southern hemisphere?
No, they see completely different ones. From the North pole you can see half the visible stars. From the South pole you can see all the others. The stars appear to move parallel to the horizon and neither rise nor set.
Are all the stars you see at night the same?
Every star you see in the night sky is bigger and brighter than our sun. Of the 5,000 or so stars brighter than magnitude 6, only a handful of very faint stars are approximately the same size and brightness of our sun and the rest are all bigger and brighter.
What are the 2 stars next to each other?
Double stars may be binary systems or may be merely two stars that appear to be close together in the sky but have vastly different true distances from the Sun. The latter are termed optical doubles or optical pairs. Since the invention of the telescope, many pairs of double stars have been found.
Are all stars the same how do they differ from each other?
Stars can be very different from each other?in color, brightness, temperature, size, and mass. For example, hot blue-white stars can reach 54,000F (30,000C) at their surface, ten times hotter than the coolest stars.
Can you see the same stars from everywhere on earth?
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.
Is a star bigger than the Earth?
Yes! In fact, most stars are bigger than the Earth. The diagram below compares the size of our sun with the sizes of the other planets in our solar system. The sun is much bigger than the Earth, and it isn’t even a particularly large star.
What is a star Twin?
Like a pair of twins, two stars shine prominently in the evening skies of the Northern Hemisphere spring each year. They are Pollux and Castor in the constellation Gemini the Twins. Pollux, also known as Beta Geminorum, is slightly brighter than Castor. It shines with a golden glow while Castor appears whiter.
Where is Pollux star located?
RA 7h 45m 19s | Dec +28° 1′ 34″

What are those moving stars in the sky?
When you look up at the night sky and see what appears to be a bright star moving quickly across the sky, what you’re really seeing is a satellite that’s reflecting the Sun’s surface in just the right way for you to see it.
Why do different stars appear in the sky at different times?
What causes different stars to appear in the sky at different times of the year? There are two major motions affecting the Earth: its rotation around its axis, and its rotation around the Sun (which we call ‘revolution’). While the rotation of the Earth on its axis causes the nightly movement of the stars across the sky,
Is the sky we see the same everywhere?
No, the sky we see is not the same. At any point on earth at any given time, about 1/2 of the entire possible sky will be visible (basically, think of the sky above you as a giant “dome” which is equal to 1/2 of the entire sphere around the earth).
Why can’t we see stars in the opposite direction of the Sun?
On a given day (meaning on a given position on the orbit), you will only be able to see the stars that are in the opposite direction to the Sun. All the stars that are ‘behind’ the Sun won’t be visible during that day, because they are above the horizon during the day (and we can see stars only during night)!
Can you see the Stars behind the Sun?
Take a look at the image above. On a given day (meaning on a given position on the orbit), you will only be able to see the stars that are in the opposite direction to the Sun. All the stars that are ‘behind’ the Sun won’t be visible during that day, because they are above the horizon during the day (and we can see stars only during night)!
