The planets appear to move through the background of stars because?
the planets orbit the Sun at varying speeds, causing them to appear to move against the fixed backdrop of stars as seen from Earth. This apparent motion is due to the Earth's own movement around the Sun, which creates the illusion of planets traversing the sky over time.
The planet that moves through the background of stars most slowly is?
The planet that moves through the background of stars most slowly is Mercury. This is because Mercury is the closest planet to the Sun and has a shorter orbit period than the other planets, resulting in a slower apparent motion against the background of stars as seen from Earth.
Why do the positions of the planets change in relation to the background of stars?
The positions of the planets change in relation to the background stars due to their orbits around the Sun. As the planets move along their orbit at different speeds, their position relative to the background stars appears to change from our perspective on Earth. This phenomenon is known as planetary motion and is a result of the planets' orbital dynamics.
Why do planets appear brighter than stars?
Planets appear brighter than stars because they reflect more sunlight and have larger apparent sizes in the night sky compared to distant stars. Stars emit light due to nuclear fusion in their cores, while planets reflect light from the Sun, making them appear brighter to us on Earth.
Why do the planets appear to move through the constellations instead of with the constellations as Earth rotates?
The apparent movement of planets through the constellations is due to the combined effect of Earth's orbit around the Sun and the orbit of the planets themselves. As Earth moves in its orbit, the perspective from which we view the planets changes, creating the illusion of them moving relative to the background of fixed stars in the constellations.
How do you distinguish between a star and a planet?
Stars in the night sky appear fixed, since they are much further away than planets. The planets can be identified through their apparent brightness and their movement among the background stars over time.

How are planets distinguished from stars on the celestial?
planets appear to move
Why do the sun and planet appear to be moving through fixed stars?
The Sun and orbiting planets are MUCH closer to the Earth than other stars.
The planet that moves through the background of stars most slowly is?
The planet that moves through the background of stars most slowly is Mercury. This is because Mercury is the closest planet to the Sun and has a shorter orbit period than the other planets, resulting in a slower apparent motion against the background of stars as seen from Earth.
Why do the positions of the planets change in relation to the background of stars?
The positions of the planets change in relation to the background stars due to their orbits around the Sun. As the planets move along their orbit at different speeds, their position relative to the background stars appears to change from our perspective on Earth. This phenomenon is known as planetary motion and is a result of the planets' orbital dynamics.
How did the ancients distinguish between planets and stars in the night sky?
Ancients distinguished between planets and stars in the night sky by observing that planets move relative to the fixed background of stars, while stars maintain their positions.
Why do planets appear larger then stars?
because they're way closer than the stars
Why do planets appear brighter than stars?
Planets appear brighter than stars because they reflect more sunlight and have larger apparent sizes in the night sky compared to distant stars. Stars emit light due to nuclear fusion in their cores, while planets reflect light from the Sun, making them appear brighter to us on Earth.
Why do planets appear in different locations in the night sky while stars in a constellation stay in the same place?
Because the stars are very far away and are suns like our Sun. The planets however are in orbit round our Sun and relatively close to us. We can therefore see the movement of their orbit against the background of the "fixed" stars.
Why do the planets appear to move through the constellations instead of with the constellations as Earth rotates?
The apparent movement of planets through the constellations is due to the combined effect of Earth's orbit around the Sun and the orbit of the planets themselves. As Earth moves in its orbit, the perspective from which we view the planets changes, creating the illusion of them moving relative to the background of fixed stars in the constellations.
How can an observer from earth distinguish planets from stars?
-- The planets you can see with your naked eye are generally brighter than a typical star. -- They also twinkle less than the stars do. -- Planets appear as small disks even in binoculars or small telescopes, but stars never do. -- From one night to the next, or certainly from one week to the next, the patterns formed by stars don't change, but planets move through those patterns.
