It is because of the Earth revolving around the Sun.
What else can I help you with?
Can you see the same stars all around the world?
You can not see the same stars all around the world. There are different star alignments in different parts of the world. For example, you can not see a star that is in Africa in the United States.
What star is 40 degrees north in the sky?
At 40 degrees north latitude, you would not be able to see any particular star directly overhead as the celestial sphere rotates throughout the night. Instead, you would see a variety of different stars and constellations depending on the time of year and time of night.
How did people use the stars as a calendar?
You can tell the time of year by looking at the stars in the sky. The ones you see tonight are the same ones you will see in any year on this date. You will see the same ones tomorrow night, but if you go out at the exact same time to look as you did tonight, you would see they were in slightly different positions. As the year continues you will notice that the stars you see are moving and you will start to see different ones. In 6 months from now, most of the stars you will see will be different than what you can see tonight, except for some that are right overhead. So if you can learn what stars are seen at what time of year, you can know what time of year it is and even work out what time it is. That is what people did long, long ago.
What is a star the definition of a star?
A star is a floating ball of flaming gas out in space. There are many different types of stars depending on what stage they are at in their life time. For instant, there are the Red Giants, and even black holes were once stars see more in a star's life time.
Why do we see different star constellations in the night sky at different times of the year?
We see different star constellations in the night sky at different times of the year because of Earth's orbit around the Sun. As Earth moves along its elliptical path, our nighttime view of the stars changes, revealing different portions of the celestial sphere. This shift occurs because we are looking out into space from different angles throughout the year. Consequently, certain constellations become visible at specific times while others fade from view.
Why do you see different constellations at different times of years?
Because Earth moves, and it appears that the constellation moves. It just seems that we see it at a certain time of year.
Do you have see the same stars and constellations at different times of the year?
Yes we do, we all see the same star every night. But if you are in a certain spot you can see the constellations. Not all can see the constellations. If you can you are very lucky.
What time of the year is the Milky Way visible?
Every star you see is in the Milky Way, so you can say it is visible throughout the year. A particular line that looks like a trail or a sort of milky way goes through the night sky and can also be seen all year round in different constellations.
What happens to the observed position of a star as Earth orbits the sun AND what is it called?
A closer star can be seen to shift positions slightly against much more distant stars as the earth orbits the sun. At one time of year we would see this star from one angle, while 6 months later, when earth is on the other side of the sun, the same star may be in a very slightly different position as we see it from a slightly different angle. This is known as parallax. It's good for measuring local star distances, but other methods are required for measuring distances of much further stars.
Can you see polaris all year?
Yes, you can see Polaris all year... it's the North Star.
Which planet called envenging star?
Venus is called the evening star and the morning star at different places in its orbit. Venus circles the sun in less time than the Earth so there is a time about every 19 months when it comes very close and overtakes us. When that happens it is between us and the Sun, and occasionally we can see it as a black dot cossing the Sun's disk (but not every time). In the 6-8 weeks before that happens we see it as the evening star, setting after the Sun, and in the 6-8 weeks afterwards it rises before the Sun and we see it as the morning star.
Why you see different constellations at different times in the year?
because the world is in different places around the sun at different times of the year therefore you would see different constalations
