• Satellites can be natural, such as moons around planets, or artificial, such as the RADARSAT satellites and the International Space Station

<aside> 🪐 The speed $v$, of a satellite in uniform circular motion around a central body depends on the mass of the central body, $m$, and the radius of the orbit, $r$. $v = \sqrt\frac{Gm}{r}$

• For a given orbital radius, a satellite in circular orbit has a constant speed
