1. The anatomy of stars (Astronomy/Large-scale structure of the cosmos)
A star is a massive, compact body of plasma in outer space held together by its own gravity and sufficiently massive to sustain nuclear fusion in a very dense and hot core. This fusion of atomic nuclei generates energy that is cont...

5. Parabolic trajectory (Astronomy/Astrodynamics)
Parabolic trajectory
In astrodynamics or celestial mechanics a parabolic trajectory is an orbit with the eccentricity equal to 1. When moving away from the source it is called an escape orbit, otherwise a capture orbit.
Under sta...
