gravity.
Electrons are located out side the nucleus in atom, and these are called as extra nuclear particles. Electrons are revolving around the nucleus as planets do round the sun
Geocentric motion of planet is that in which earth is at the centre of the universe and all other planets revolving around it.Heliocentric motion of planets is that in which sun is the of universe and other planets revolving around it.In planetary motion all the planets includes Earth revolving around the Sun in their fixed orbit.
Planets
solar system
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
because it has axis
All the planets revolve around the Sun.
The moon is Earth's satillite, revolving around earth eternally.
They rotate. Travel around the sun is called revolving.
Planets do not naturally generate nuclear fusion. Nuclear fusion occurs in stars, where the extreme heat and pressure at the core allows hydrogen nuclei to merge and form helium, releasing energy in the process. Planets lack the conditions necessary for sustained nuclear fusion reactions.
He discovered that the planets revolved around the sun instead of the planets & the sun revolving around Earth.
Planets do not collide while revolving around the sun because they follow different orbital paths with varying speeds. These paths are determined by the gravitational pull of the sun, which keeps the planets in stable orbits. Additionally, the vast distances between planets provide enough space to prevent collisions.
