Time is a universal thing, it is always there it is always progressing at the same rate never moving backwards, time may be defined as anything. Before 1960 it was defined as a 'solar day', and a second was defined to be (1/60)*(1/60)*(1/24) of a solar day, then in 1967 we changed to the atomic clock which measures vibrations of cesium atoms, now one second is defined to be : 9192631770 times the period of vibration of radiation from the cesium-133 atom.
like i said time may be defined by anything
Technically yes, but it is too small to measure with any accuracy, though it can be calculated.
No body knows at this time.
probaly because the planets didnt have names and everything was happening on earth
Yes the Earth does rotate like the other planets (except for the distance of the rotation(assuming your talking about the rotation around the Sun); the wobble of the Earths axis compared to other planets; and the time it takes to rotate)
As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.
They have very minor gravitational effects. Not noticeable but can be calculated.

All the planets of our solar system are believed to have formed at about the same period in time.
Speed is calculated by dividing the distance traveled by the time taken to cover that distance.
At this time we have no evidence of any extraterrestrial life.
Yes.
No. It holds for other planets, and for any other situation where one objects orbits another - for example, moons orbiting planets, stars orbiting a black hole, etc.
because the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other.Answerbecause the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other. the planets each have defined Elliptical, not circular, orbits that remain constant because of gravitational pull of the sun and from each other. Pluto does have such an elliptical orbit that for a time it was closer than Neptune, but they will never collide with their current paths.
The time it takes for the Earth and other planets to go around the sun is mainly influenced by their distance from the sun. Closer planets have shorter orbital periods due to the stronger gravitational pull of the sun, while farther planets have longer orbital periods due to weaker gravitational forces. This relationship is described by Kepler's Third Law of Planetary Motion.
The other planets are not similar to dwarf planets.
The other planets do have gravity.
