they don't really appear they were made by astronomers who looked at the sky and made patterns and said what it was. like for example cancer it is like a y in the sky and its a crab its like looking up at the clouds they just looked at the stars basically connected the dots
Earth revolves around the sun. That is why the constellations we see from Earth appear to change.
They are called constellations.
No. Constellations are arrangements of stars that appear to form pictures.
after sunset and before sunrise
They're generally named for the constellation they appear to originate from. For example, the Leonids appear to radiate from a location in the constellation Leo, and the Perseids from a location in the constellation Perseus.
Stars and constellations appear to move in the night sky due to the Earth's rotation on its axis. As Earth spins, different stars and constellations become visible while others disappear below the horizon. This motion gives the illusion of stars and constellations moving across the sky.
Constellations appear to form images in the night sky, but each of the stars are extremely far away fron each other. They just line up from our own viewing points.
Periodic showers which, due to their position and trajectory, appear to originate from specific constellations are named for that constellation.
Stars and constellations appear to rise and set due to the rotation of the Earth on its axis. As the Earth rotates, different stars and constellations come into view or move out of view from a specific location on Earth, giving the illusion of them rising and setting.
The constellations would not appear to change shape as you move because they are so far away that the relative positions of the stars remain constant from our viewpoint on Earth. This is why we can use constellations for navigation and timekeeping.
Constellations appear to move in the sky due to the Earth's rotation on its axis. As the Earth rotates, different constellations become visible at different times of the night. This motion is also why constellations appear to shift positions throughout the year.
Because of Earth's rotation.
