Earth moves faster in its orbit around the sun when it is closer to the sun, which happens in December. This is due to the conservation of angular momentum in the solar system, where the closer a planet is to the sun, the faster it moves in its orbit.
The speed of a planet in its orbit around the Sun primarily depends on the planet's distance from the Sun. Planets closer to the Sun move faster in their orbits compared to planets farther away due to the gravitational pull of the Sun. The mass of the planet also plays a minor role in determining its orbital speed.
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
it moves around the sun
Because the sun moves around so when the sun moves around the light from the sun touches the planets
Sedna.
A planet moves along its orbit around the sun in an elliptical path due to gravitational force. The planet travels at varying speeds, with faster speeds near perihelion (closest point to the sun) and slower speeds near aphelion (farthest point from the sun).
Pluto is the slowest planet to move around the sun, because of its far distance.
Mercury.
No. Earth moves in an ellipse around the Sun; when it is closest to the Sun (at its periapsis, in January), it moves faster, and when it is furthest from the Sun (at its apapsis), it moves slower.
A planet orbits a sun, a moon orbits a planet
All of them do.
