Orbital decay is a gradual decrease of the distance between two orbiting bodies at their closest approach (the periapsis) over many orbital periods. These orbiting bodies can be a planet and its satellite , a star and any object orbiting it, or components of any binary system .
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 ...
At higher altitudes, where air drag is less significant, orbital decay takes longer. Slight atmospheric drag , lunar perturbations , Earth's gravity perturbations, solar wind , and solar radiation pressure can gradually bring debris down to lower altitudes (where it decays), but at very high altitudes this may take centuries.

Simplified Deep Space Perturbations (SDP) models apply to objects with an orbital period greater than 225 minutes, which corresponds to an altitude of 5,877.5 km, assuming a circular orbit. [ 3 ] The SGP4 and SDP4 models were published along with sample code in FORTRAN IV in 1988 with refinements over the original model to handle the larger ...
According to game designer Phil O'Connor, O·R·B was designed to take a different approach on the RTS genre, emphasizing the "strategy" therein. [4]The storyline also received significant attention, as the developers wanted to move away from the rehashed alien stories in other space simulation games.
Orbit Downloader is a discontinued download manager for Microsoft Windows. Launched in 2006, its developers abandoned it in 2009. [ 4 ] In 2013, Orbit Downloader was classified as malware by antivirus software after ESET discovered a botnet in the application.
Core Decay is an "atmospheric immersive sim. [1] The game is experienced through a first-person perspective, and focuses on exploration of the game world to accomplish goals. The player can interact with NPCs, collect logs and messages, hack computer systems, and engage in combat with enemies. First-person shooting is a core game mechanic ...
