How long will it be then before all the Sun's mass is gone?
Divide the total mass by how much mass it loses each second.
Mass/loss-rate = (2 x 1030 kg) / (1010 kg/s) = 2 x 1020 seconds, or just over 6 thousand billion years.
Don’t worry though, a lot of other things will happen to the Sun long before this loss of mass becomes a problem. |
