I'll have hard time devicing my answers... Assume that planet can develop life. Have any edeas about? More mass the planet have, greater is its gravity. But could be planets bigger then the Earth but with minor or equal mass?

Yes, actually my interest for the question is more sci-fi, perhaps i should specify it. Yes, i figure it out! A 20 years period needs hotter star. Is so impossible esteem the distance? Where can i find this table of line online? Aside from this.. Could a reasonable fraction are...

Thanks! Now, soppose there's a planet with plenty time orbital period compared the earth's. For example 20 time, so 20 years. The planet's distance and the dimension of central body must be enough such to let the life exists. How much the planet's average distance or then, the semi-major...

Yes, then, what's the average radius for allipses? Is for instance UA the average radius?

Interesting but I'm an amateur, my brain is easily engulfable, what's the mean radius?

Sorry, i forgot to specificy that's orbital revolution! Thanks anyway Then according to Kepler's third law in my instance the planet in question would has the same orbital revolution then the earth.

Hi dudes, My questions are: What does planet's revolution depends? If for example is there a planet 4 time the mass of the Earth at about its same distance from a star 4 time the mass of sun, could it be it has the same revolution period ot the eath?
