Why does the position of the constellation Orion appear to change throughout the year and why can't Orion be seen in the summer sky?

The reason is that as Earth travels round the Sun in 12 months, the stars that are visible at midnight each night shift slowly by about 1 degree every 24 hours so that a complete circle round the sky is completed once a year.
In the opposite direction is the Sun, and the Sun moves across the background of stars also competing a circle every year. In the summer the Sun is approximately lined up with Orion so that the stars of Orion can't be seen because of the glare from the Sun. Actually, Orion is visible in the summer sky, to the east just before sunrise in the Northern Hemisphere.

How does the big dipper change with the seasons?
From the viewpoint of the Earth, all the constellations 'revolve' around Polaris (the North star. As the Earth orbits the sun, its relative position to the constellations changes - and they appear to move across the night-sky.
In which constellation does Mars appear in the sky?

Which planet Mercury or Venus changes position the most with respect to the sun?
Mercury changes position the most with respect to the sun. It has the shortest orbital period of any planet in our solar system, so it completes its journey around the sun faster than any other planet. This causes it to appear to change position relative to the sun more frequently.

Name and position of satellites are in the sky?

The fact that the position of the constellation seems to change throughout the year is evidence that?
It is evidence that the earth orbits around the sun.
Why do constellation change position during the night?
Constellation change position during the night due to the earth's multiple motions, such as the wobble and rotations around the sun.

Does the constellation Eridanus change from hour to hour and if so what direction does it move in?
Yes, the constellation Eridanus appears to move across the night sky due to Earth's rotation. It generally moves from east to west as the night progresses. This motion can vary slightly depending on the time of year and your location on Earth.
Why does the shape of a constellation appear not to change?
The shapes do change, but only a little bit over thousands of years.
What cause the position of a constellatioon to appear to change at the same time of the evening over a period of several weeks?
This is a result of the earth's orbiting the sun. We are looking at the constellation from a different angle as the weeks progress.
What causes the position of a constellation to appear to change over a period of several hours?
On a daily basis, the rotation of the Earth. On a seasonal basis, the motion of the Earth around the sun. Over the long term ... they're all independently moving around the center of the galaxy.
Why do the constellations seem to move as the seasons change?
As the Earth goes around the sun, it changes its position relative to the stars in those constellations. At times, some stars won't be visible as they will be behind the sun. This change in perspective isn't enough to make it appear as if they stars have taken a radically new position. They still seem to be just where they always have been. That's why the stars of each constellation stay in the shape of the constellation and instead it seems as though the whole constellation moves. Really, it's just us that are moving.
Is position of the constellation seem to change thoughout the year?
Only if you look at it at the same time every night. If you look at it 4 minutes earlier each night, then it doesn't change position at all.
Why does the Sun appear to change its position throughout the day?
Type your answer here... Because the Earth is rotating on its axis. As the world turns throughout the day, the Sun "appears" to change position from East to West. But actually, it is Earth that is rotating. It it is like driving in a car. When you see a sign coming up, it looks like it is getting closer and then it goes by you. The sign was not moving. You were in a car that was moving.
How do you know if a constellation is circumpolar?
It is a constellation that never sets due to its proximity to one of the celestial poles. This means that unlike some constellations, it is always visible on any clear night of the year. You will notice when you observe it throughout the year, that it does seem to change position, as it rotates around the celestial pole. Ursa Major is probably the best known of them.
When does Hercules star constellation come to the southern hemisphere?
Hercules is a constellation of the Northern sky, the constellation does not change position and so will never come to the Southern hemisphere. To see everything astronomers need to visit countries in both the northern and southern hemisphere.
