Solar System Satellites

Introduction to solar system satellites:
A satellite is an object that goes around any other body. Natural satellites are celestial, such as a moon that orbits a planet, which is called the primary in a solar system. A natural satellite is a non-artificial satellite of planets. They are also called as moons. They vary in size but are generally smaller than the planet they orbit.Most of the satellites were discovered before the 20th century by visual observations from the Earth, by astronomers like Galileo Galilee, Copernicus and Simon Marius

The more distant planets and their satellites were discovered by means of space probes and super telescopes in the modern technical era of the 20th century. Our solar system has more than 140 natural/ celestial satellites.I like to share this what is conservation of energy with you all through my article.


Satellites of our solar system


Our solar system has nine planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune And the dwarf planet Pluto. Except for Mercury and Venus, all the planets of our solar system have their own satellites.The few planets which have large satellites are Earth, Jupiter, Saturn and Neptune.

Dwarf planets, other solar system bodies, asteroids and Neptunium objects also have satellite but are not named yet. These satellites orbit around their primary planet in the solar system.

Earth has a single large moon. This was first observed by Galileo in the 17th century, to have bright mountains, dark plains and be marked by craters.

Mars has two very small satellites.The 4 bright satellites of Jupiter are easily visible with small telescopes and were discovered by Galileo.Saturn has one bright satellite which is visible with the telescope, the rest have very low light.


The Planets and their moons in our solar system:

The following are the listings of the natural satellites of the various planets we know:

Mercury has none, neither Venus.
Our Earth has only one moon.
Mars has Deimos and Phobos.
In case of Jupiter- numbered 62, they are callisto, Europa, Amalthea, Elara, Pasiphae,Sinope, Isonoe,Sponde, Kalkye,Thebe, sponde.
Saturn has around 33,Titan, Dione, Tethys, Mimas, Pandora, Janus, Tarvos, Skadi, Telesto, Calypso,
Uranus has around 27, they are Ophelia, Biance, Cressida, Juliet, Portia, Rosalind, Puck, Titania, Galatea.
Pluto, which is no more a planet, used to have only 1 and that is Charon.

Having problem with Buoyancy Formula keep reading my upcoming posts, i will try to help you.

Conclusion to solar system satellites


Most of the planets have satellites that are too tiny or too far and give very little light to be visible with a telescope from the earth.Charon is so big that it is paired with Pluto and considered to be a double dwarf planet.
