Mercury orbits the Sun in @88 Earth days. So if you divided 365 days in a year by 88 the result comes to about @ 4 Earth days. A decade is 10 years so multiply 10 by 4 and you get @ 40 days or as you say 41 times.
The orbit of the planets in our Solar system are not perfectly circular, but eliptical. Each planet also has its own unique orbit, no two planets share an identical orbit. Because of the elliptical (oval) orbit of planets some get close to each other or cross the path of another planet's orbit.
Yes, each of the 8 major planets has its own orbit, with no asteroids or other objects in its path.
orbit
No they each have its own orbit around the sun and they do not collide
planets dont "switch" orbit, but there are those that orbit each other, and those, like mars, that have retrograde motion, which makes it appear to orbit backwards
Planets do not take steps. Each planet has its own orbit and is is different.
The Sun AND its planets attract each other with gravitic force.
the planets would have dashed each other
The sun, each of the eight planets is in orbit around our sun.
So they don't run into each other.
Each planet has an orbit line that makes the planets stay in that spot, unless the orbit is changed
Galileo used the telescope to support the heliocentric model (Planets orbit the sun)Nicolaus Copernicus worked out the arrangements of planets and how the move around the sun (heliocentric).Tycho Brahe and Johannes Kepler researched the planets' orbit and found that the orbit of each planet is an ellipse (Oval shape).
