Why does the constellation of Orion seem to move?

Answer 1

There are two things that cause the constellations to appear to move.

1. The first is the earth's rotation, this causes the zodiac constellations to rise in the east at dusk move across the sky at night and set in the west at dawn just like the Sun moves across the sky during the day. Those constellations that appear near the north or south polar areas of the sky don't rise and set, they simply rotate during the night.
2. The Earth rotates once a year round the Sun and as the zodiac constellations are arranged in a circle round the Sun in the plane of the Earth's orbit, as the Earth orbits the sun different constellations will be visible in the night sky at different parts of the orbit. This too causes the constellations to appear to move, for instance Orion is visible in the night sky during the northern winter but is on the opposite side of the Sun to Earth during the summer (and therefore not visible)

The earth does not rotate once a year round the sun, its called orbiting, rotate is spinning and orbit is moving around an object. Earth is a satellite of the sun.

Answer 2

The movement of the constellation of Orion in the night sky is due to Earth's rotation. As the Earth rotates on its axis, different constellations appear to rise and set. This creates the illusion of movement in the night sky.

Answer 3

The entire sky seems to move around us once every 23h56m, due to the Earth's rotation.

Answer 4

Stars near the celestial pole appear to move in circles around the Pole Star, which is Polaris. Polaris appears to be DIRECLY ABOVE the north pole, but it is actually about 3/4ths of a degree off.

If you aim a camera at Polaris and make a long time exposure, you'll see that Polaris makes a tiny little circle, with other stars making bigger circles around it.

Answer 5

You can't see stars when the sun is up. In order to see stars, you always look away from the sun.

Six months from now, we will be halfway through our annual orbit around the sun.

The direction you face to see the sun today will be the direction you face to see the night-time

stars in six months from now.

The direction you face to see the stars tonight will be the direction you face to see the sun

in six months from now.

The stars you see over your house at 10:00 PM tonight are in exactly the opposite direction

from the stars you'll see over your house six months from now at 10:00 PM.

They're different stars, in different random patterns.

Answer 6

If you were riding on a spinning merry-go-round (carousel) but didn't know it, it would appear to you as if

your parents, friends, and everone else standing around out there were turning around you, all together.

You are riding on a spinning earth but can't feel it. It appears to you as if the sun, moon, and everything else

out there is turning around you, all together.

It's your eyes that are constantly being turned to point in a constantly-changing direction. In order to

keep watching the same star, you have to keep turning your eyes, and it feels as if the star is moving.

Answer 7

This phenomenon is due to something called parallax. If you hold your finger at arms length and close your right eye, then close your left eye and open your right, your finger appears to move, even though you are holding it still. It is because your point of observation has changed. If you hold your finger closer to your face, the distance it appears to move becomes greater. Now imagine the sun being the center of your face, and each eye as an opposite point on the earth's orbit. Stars that are closer to the earth will appear to move as compared to stars that are farther away.

Answer 8

The constellations and stars that make them up don't move, they remain in the same place. In contrast, the Earth spins on its axis as it revolves around the sun, so people on earth see different parts of the sky at different parts of the year.

Answer 9

Both. They just move almost imperceptably due to their distance from the earth. We notice their movement across the sky due to the rotation or the earth. The movement you see of the stars is from the Earth's rotation, same thing that moves the sun and moon.

Answer 10

Many things. The movement or rotation of the Earth on it's axis, the revolution of the Earth around the Sun and the revolution of our Solar System around the central core of our galaxy, the Milky Way. Also, the stars may well be part of their own galaxy, so they will also revolve around their centre.
