Yes.
The closer planets are to the Sun the faster their orbit speed
Planets and comets move faster when they are closer to the sun.
Planets and comets move faster when they are closer to the sun.
A planet's distance from the sun affects its orbit speed through Kepler's Third Law of Planetary Motion. The closer a planet is to the sun, the faster it travels in its orbit. This is because the sun's gravitational pull is stronger closer to the sun, causing the planet to move faster to maintain its orbital balance.
Planets closer to the sun move faster in their orbits due to the stronger gravitational pull from the sun. This increased speed helps to counteract the stronger pull of gravity, allowing them to maintain a stable orbit.
Gravity. The closer a planet is to the sun, the faster it must move to keep from falling into the sun. So note; the closer in; the smaller the orbit AND the faster the speed.
You may recall that the force of gravity is inversely proportional to the distance between the centers of mass of the objects in question. Hence, objects closer to the sun are much more strongly attracted by the sun. They must balance that force by a stronger centrifugal force which requires a faster orbit. If they did not do so, they would just fall into the sun and be gone. Only the fast survive.
Planets Mercury and Venus are closer to the Sun than Earth.
Planets orbit the sun at different speeds because they are at varying distances from the sun. According to Kepler's laws of planetary motion, planets closer to the sun have faster orbital speeds, while those farther away have slower speeds. This is due to the gravitational force exerted by the sun, which is stronger on planets closer to it.
Closest to the sun
Their orbit is a smaller circle than the ones further out, and as long as they are moving at relatively the same speed they will complete each orbit faster. Check out the planetary orbits link, it gives a really cool description and moving diagram
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.
