Question

How far is Pluto from the earth in km?

Answer 1

Planets are usually in the shape of a spheroid. Planets do not produce light and they are smaller than stars. The objects that orbit the planets are called Satellites.

Complete solution:
The chemical composition of pluto consists of a mixture of 70% of the rock and 30% of the water ice and the pluto has a rocky core which is surrounded by a mantle of the water ice with more exotic ices like carbon monoxide, methane, etc.
In our solar system, other than the Earth, Pluto is the only place that is known for having white peaked mountains that are made up of methane frost. Its surface is covered with ices and will have several mountain ranges, a scattering of the craters, and also with light and dark regions.
Even though Pluto is an outer planet, it is smaller than several moons.
Whenever the two bodies are on the opposite sides of the sun, Pluto will be at a distance of 7.5 billion kilometers and when they are closer to each other, then Pluto will be at a distance of 4.28 billion km.

Note: 1. Earth is made up of three different layers namely the core, the crust, and, the mantle. The outside layer of the earth is made up of solid rock like granite and basalt. The thickest layer is the crust and the inner core is solid.
2. In our solar system, Pluto is still not an official planet. It is the fourth brightest celestial object after the sun, the moon, and Venus.
