The Sun and orbiting planets are MUCH closer to the Earth than other stars.
Not really. The planets - even the slow moving ones further out, are constantly moving around the sun and are therefore always moving against the background stars, which are fixed.
The celestial object that appears to move backwards among the stars is a planet in retrograde motion. This happens when a faster-moving planet "laps" a slower-moving outer planet from the viewpoint of Earth, causing it to look like it is moving backwards relative to the fixed stars in the sky.
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.
Planet comes from an ancient Greek term meaning 'wanderer'. They were called wanderers because they appear to move against the apparent stationary background of stars.
The motion of a train on a moving track depends on the reference frame you choose. In the train's frame of reference, it may appear stationary or moving at a constant speed. However, in an external, stationary frame of reference, the train would appear to be moving at a different velocity that combines the train's speed with the speed of the track.
The surface generated by a straight line, the generator, passing through a fixed point, the vertex, and moving along a fixed curve, the directrix.A right circular cone.
The word "planet" comes from the Greek word "planētēs," which means "wanderer." This term was used because the planets in our solar system appear to move across the night sky in relation to the fixed stars.
All the planets move continuously among the fixed stars, so they were called the wandering stars.The planets all move in or near a fixed plane. As they wander they all appear to stay close to the plane of the Earth's orbit, which is the ecliptic.
Since Earth's surface is rotating toward the east, "fixed" celestial bodies appear to be moving toward the west.
A static frame is a fixed reference point with respect to which motion is described, while a moving frame is a reference point that is in motion relative to the objects being observed. In a static frame, objects appear stationary, while in a moving frame, objects may appear to be moving even if they are stationary in the static frame.
Not moving; not appearing to move; stable; fixed., Not improving or getting worse; not growing wiser, greater, better, more excellent, or the contrary., Appearing to be at rest, because moving in the line of vision; not progressive or retrograde, as a planet., One who, or that which, is stationary, as a planet when apparently it has neither progressive nor retrograde motion.
A retrograde motion of an OUTER planet happens when Earths orbit catches up with and overtakes the planet as Earth orbits the Sun. For Jupiter it is observed to be in retrograde (moving backwards as measured against the fixed stars) motion for 121 days a year. NOTE Jupiter is not actually moving backwards, it just appears to.
