There are different categories in Exoplanets such as Hot Jupiters, Super Earths, Trappist System, Super Puffs, Neptune Worlds, Super Gravity, etc. One lightyear is equal to 9.46 trillion kilometers! It is a unit of distance and not a unit of time. A 'lightyear' is the distance traveled by light in one year. They too follow a planetary system similar to our solar system and are scattered several lightyears around us. Planets in the Milky way galaxy beyond our Solar system are referred to as Exoplanets or Extrasolar planets. In fact, Jupiter and Saturn are Gas giants whereas Uranus and Neptune are Ice giants. Planets Jupiter, Saturn, Uranus and Neptune are referred to as outer planets. Planets Mercury, Venus, Earth and Mars are often referred to as inner planets and have a solid surface. There are 8 official planets in our Solar System which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. This app allows you to visualize the force of gravity of each planet by dropping an object such as an apple from a height of 1 meter. Extending this principle to planetary bodies, each planet in our Solar System, which has its own gravitational field will attract other masses. This force of attraction is proportional to the product of their masses and inversely proportional to square of the distance between them.Īccording to this law, all objects that have mass will attract other masses. According to the law, any two masses anywhere in the universe separated by a distance will attract each other. The universal law of gravitation was coined by Sir Isaac Newton. Planet Gravity currently has 5 reviews with average vote value 4.6 Gravity is derived from the Latin word ‘gravitas’ meaning mass. According to Google Play Planet Gravity achieved more than 2 thousand installs. Android application Planet Gravity developed by Srinath Srinivasan is listed under category Entertainment.
