Suppose we found a solar system with the property described below. In light of what you have learned about the formation of our solar system, decide whether the discovery should be considered reasonable or surprising. (a): A solar system has 15 planets that all orbit the star in approximately the same plane. The two planets closest to the star are terrestrial and the rest are gas planets?

Surprising

Explanation:

This is surprising because the total number of planets in our solar system are nine which revolve around a central star i.e sun in different orbital paths.  

Also, out of 9 nearly four planets i.e Mercury, Earth, Venus and Mars are terrestrial i.e having some land forms. Out of remaining 5 non terrestrial planets nearly four planets are gas planets (Jupiter, Uranus, Neptune and Saturn) and these planets are distantly positioned from the central star

Hence, the given discovery is surprising

currents is the correct answer.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
