Structure & Composition of Solar System
The solar system consists of the Sun which is an average star in the Milky Way Galaxy & we have bodies orbiting around it: 8 (formerly 9) planets with certain known planetary satellites (moons); countless asteroids, some of which have their own satellites; comets & other icy bodies; & vast reaches of highly tenuous gas & dust known as the interplanetary medium.
The sun is located at the center of the solar system & it influences the motion of all the other bodies through its gravitational force The planets, in order of their distance outward from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, & Neptune.
Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body which includes asteroids, meteoroids & comets. An asteroid is a minor planet of the inner Solar System. They are metallic or rocky bodies without atmospheres that are too small to be classified as planets & are basically remnants left over from the early formation of the Solar System.
A meteoroid is a small body that moves in the solar system & would have become a meteor had it entered the Earth’s atmosphere. A comet is an icy, small body in the solar system that warms & begins to release gases while passing close to the Sun.

Planets in our Solar System
Planets in our Solar System: Over several years, we have seen how humans have been interested in exploring various planets that are found in our solar system. From the very first launch in the late 1950s till the present, various probes, orbiters, landers & rovers have been sent to every planet in our solar system. The “planet” word is derived from the word “planets,” meaning wanderer.
Planets are celestial bodies that orbit the sun in a fixed orbit; they do not emit their light but reflect sunlight. As they are too close to the Earth, they don’t twinkle like other stars. To date, Earth remains the only planet to support life & have a favorable environment.
This article explores the origin & formation of the solar system, along with all the planets in our solar system in detail.
