Q&A

What mass for my space station to have enough gravity to attract satellites?

+0
−0

Think about a big space station or whatever giant space building.

What will be its mass to attract (with gravity):

  • Small asteroids (1-10 kg / 2-20 lbs)
  • Spaceman (100 kg / 220 lbs)
  • Satellites (1000-10 000 kg / 2.200-22.000 lbs)
  • Ships or more (100 000+ kg / 220.000+ lbs)

Example : the ISS is about 400 000 kg (881.000 lbs). Does it attract things?

EDIT : To simplify, consider this building alone in outer space, with no external influence (other planets, solar winds, whatever).
