Questions regarding Universe Sandbox, software that simulates astrodynamics.
At high temperatures, do planets glow like blackbodies?
I've been messing around in Universe Sandbox for a while and noticed that as a planet heats up, it glows like a blackbody starting at ~4000 K. Is the simulation here accurate, or do very hot planets ...
Why doesn't smashing larger and larger bodies incrementally into a rocky planet create a star?
Let's start with a stationary Earth. If we smash a few Mercury-sized objects into the Earth, the Earth begins to accrete mass. Repeat this step with larger and larger objects, until we start impacting ...
Easy interactive visualization of orbital elements
To get a grip on orbital elements, I'd like to play with a ready interactive visualization like in Universe Sandbox. E.g. drag the inclination slider and see immediately what happens to the satellite ...
Could Planet Nine be much smaller than thought previously?
In 2016, Caltech astronomers began testing a Planet Nine hypothesis to explain the eccentric and inclined orbits of distant dwarf planets such as Sedna, 2015 TG387, Niku, and 2012 VP113. The ...
What is the smallest diameter black hole that can be formed naturally?
I was watching the video I Put a 1mm Size Black Hole Next to Earth and This Happened - Universe Sandbox 2 discussing what would happen if a 1 millimeter black hole is orbiting the earth, and I began ...
Is a General Relativity approximation available in Universe Sandbox (1 or 2)?
This answer points out that including General Relativity in a simulation can be computationally intensive and may not be present in Universe Sandbox. However, answers to How to calculate the planets ...
Universe Sandbox 2 accurate representation of gravity
I've been playing Universe Sandbox for a while now and I have never been able to make a near Earth asteroid collide with it. By "make" I mean, simulating billions of years of known, near Earth objects ...
2 Earth-like planets in co-orbital configuration
I am trying to set up 2 Planets in a co-orbital configuration around a Jupiter size planet similarly to Saturn's moons Janus and Epimetheus. I'm trying to do this in Universe Sandbox 2 but when I ...
Is Universe Sandbox 2 realistic?
Universe Sandbox 2 is the second installment of Universe Sandbox that is available on Steam. It is an educational simulation game based on astronomy and anything space, it ranges from supernova ...
