The farther the planet is from the sun, the longer its orbit, the distances between the planets differ in their distance from the sun, and there is an inverse relationship between the distance of the planet from the sun and the length of the orbit. It took place in the late fifties of the last century until now, at the time of sending probes and orbital vehicles to land and identify the planets. In the solar system, we will learn about the planets and the solar system, and we will not forget the answer to the validity of the above statement.
types of planets
It includes eight planets, but Pluto, which has other characteristics, is excluded from it, and these remaining eight planets are divided into the inner or terrestrial planets and the outer planets, which are called Jovian planets, which differ from each other in terms of their proximity to the sun or their basic composition
- The inner or terrestrial planets are the four innermost planets in the solar system, Mercury, Venus, Earth and Mars, which are called terrestrial because they have a compact, rocky surface like Earth’s, while Venus, Earth and Mars have atmospheres. More importantly, Mercury has almost no atmosphere.
- The outer planets or Jupiter planets include Jupiter, Saturn, Uranus and Neptune and are known as the Jovian planets because they are giant compared to Earth and the rest of the planets have a small solid nucleus.
The farther the planet from the sun, the longer its orbit
The phrase is wrong because some astronomers did their studies about the planet Earth and discovered a set of laws, the law of orbits, the law of space and the law of time, and through their studies they found that many cultures of previous nations had many cultures, misconceptions about the planet Earth, and among these beliefs, that The Earth is stationary and the stars and planets revolve around it.
What is the concept of the solar system or heliosphere?
A star system that includes all forms of life, consisting of the sun and the heliosphere consisting of a giant magnetic bubble that houses most of the known objects in the solar system, including the solar wind and the entire solar system, and the sun is gravitationally bound to all celestial bodies in the system.
