According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe ...

2019 – Advanced LIGO and VIRGO detect GW190814, the collision of a 26-solar-mass black hole and a 2.6-solar-mass object, either an extremely heavy neutron star or a very light black hole. [292] [293] This is the largest mass gap seen in a gravitational-wave source to-date.
Jupiter is the biggest planet in our solar system, according to NASA. Jupiter’s radius is over 11 times the equatorial radius of the Earth.
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
Orbiter was developed as a simulator, [14] with accurately modeled planetary motion, gravitation effects (including non-spherical gravity), free space, atmospheric flight and orbital decay. [15] [16] The position of the planets in the solar system is calculated by the VSOP87 solution, while the Earth-Moon system is simulated by the ELP2000 ...
Gravity is a software program designed by Steve Safarik [1] to simulate the motions of planetary bodies in space. Users can create solar systems of up to 16 bodies. Mass, density, initial position, and initial velocity can be varied by user input. The bodies are then plotted as they move according to the Newtonian law of gravitation.
