Closest to the sun
Neptune is the slowest and mercury is the fastest
The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
Planets orbit stars.
Moons orbit around planets. They are natural satellites that are held in orbit by the planet's gravitational pull.
All planets orbit around a sun.
The closer planets are to the Sun the faster their orbit speed
Yes.
the fastest planet that orbit's the sun is mercury.
Neptune is the slowest and mercury is the fastest
Mercury and Venus
Precisely because: That's the way that gravity works.
The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
Planets and comets move faster when they are closer to the sun.
Planets and comets move faster when they are closer to the sun.
Planets orbit stars.
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Yes. The planets travel fastest at perihelion, the closest point to the sun in the orbit, and slowest at aphelion, the farthest point.
