Gravity Simulator is a simulation software package for amateur astronomers, which helps them to observe and study the universe. With the help of this software you can re-create the simulations carried out by professional astronomers.
The features of the Gravity simulation software help you to study the orbits of planets, moons, asteroids, etc. by performing the n-body simulation. The rotating frame feature allows you to understand the complex orbital relationship between the various moons of Saturn. It can also tell you the relationship between our own Earth’s orbit with the Cruithne asteroid’s orbit. More than 40 simulations are available on the web site. They include simulations of space crafts visits to Jupiter and Saturn, Saturn’s A, B and C rings. Some of other interesting simulations are the Solar System, the black hole in the Milky Way, binary star system, to name a few. The Apophis simulation shows some interesting facts. It was once believed that Apophis, also known as 2004 MN4, would impact Earth on April 13, 2029. It is now known that the asteroid will miss the Earth, it will come very close. The asteroid passes through the Earth / Moon system, barely missing both the Earth and the Moon. But if you run the simulation a few more minutes, you can watch Apophis returns to Earth's region in 2036. Once you are familiar with the existing simulations you can make your own simulations.
This colorful simulation can get attention from the young generation budding astronomers as it gives an opportunity to learn about the universe in a whole different way.
