It was Johannes Kepler who produced the theory of the planets' positions and speeds which is accepted today.
The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
No, all of the planets have different orbital speeds, dependant on many factors including the gravitational forces experienced by the particular planet.
Different Colors Of Light Travel At Different Speeds.
no
no
yes they do
Well they travel to different places such as the moon,and they travel to explore different planets.
Different plates travel at different speeds.
Astroids have not been "created". Astroids are the remains of dead planets and stars that travel through space at speeds of up to 1 million kilometers an hour. Astroids have been around since planets and stars were created.
varying speeds different colors of light travel
They travel at different speeds.
because of material density
