  The Earth’s gravity only depends on one thing – the mass of the Earth, and this isn’t going to increase any time soon!

  The only way the Earths gravity could get stronger would be by it getting more massive. Now the Earth could slowly grow mass from all the comets/asteroids hitting it, but it also slowly looses its atmosphere to space….. the mass isn’t going to change much soon, so this isn’t going to happen.

  The moon is actually moving away from the Earth by 2 cm a year! Not because of any change in the gravity, but because the moon gets a tiny bit more energy from the earth when it makes the tides, and this energy pushes the moon a little bit further every time it goes round. We don;t know if it will ever escape the Earth’s gravity, but if it did, what would life be like without the moon?!

  No, because that would mean there would be more mass on the Earth which would probably mean lots and lots (and LOTS) of asteroid strikes.
