Question

Suppose that a tiny space invader (m=0.47 kg) and the new space station orbit Earth at the same height from Earth’s surface. Which one has a greater orbital speed?

Answer 1

The tiny space invader and the new space station will have equal orbital speed.

The orbital speed of satellite

The orbital speed of satellite on Earth surface is given as;

$V = \sqrt{\frac{GM}{r} }$

where;

• V is the orbital speed
• G is universal gravitation
• M is mass of the Earth
• r is the radius of the circular path

Since the two objects are at the same height from Earth's surface, the distance from the central point (r) will be the same. Thus, the two objects will have equal orbital speed.
