Why is temperature a good criterion for searching for Earthlike exoplanets?

grandymaker [24]

Because it gives us the abilitity to find planets that have decent temperatures relative to earths temp so we can determine if the planet even has a possiblilty to sustain life hope this helps

dybincka [34]

M = 4kg
F =8N
a..?

F =m.a
8 = 4.a
a = 2m/s^2
