The first extra-solar planets detect are not likely canidates for life b/c
a) the planets are too small
b) their surface temp is too low for liquid water
c) they orbit pulsars, which emit too much powerful radiation
d) they are too distant from the star they orbit.
I believe the answer is c) they orbit pulsars, ect..
So far, it appears that extra-solar planetary systmes differ from our solar system in that
a) stars in the center of these systems are all much more massive than our sun
b) theplanetary systems are typically larger than our solar system
c) these planetary systems have no Oort cloud
d) giant planets are located closer to the central star
e) they are found around B stars
I think the answer is d.
thanks
