Answer:
Consistent with theory:
-Beyond its jovian planets, a star has two ice-rich objects as large as Mars.
-A star has 20 planets
-A star is surrounded by a disk of gas but has no planets.
-Of a star's 5 terrestrial planets, 1 has a moon as large as Earth's moon.
Not consistent with theory:
-A star's 4 jovian planets formed in its inner solar system and its 4 terrestrial planets formed farther out.
-All 6 of a star's terrestrial planets have a moon as large as Earth's moon.
-A star's 5 terrestrial planets orbit in the opposite direction of its 3 jovian planets.
-A star has 9 planets, but none orbit in close to the same plane.
Explanation:
The nebular theory postulates the formation of our solar systems. According to this theory, the solar system started as gas and dust which later collapsed, heating up as they did and separating into two planet types.
The different planet types created were the terrestrial, forming on the inside and the Jovian planets which formed outside of the solar system.
Jovian planets are ice-rich and developed by drawing the gas present in the nebula. Phenomena consistent with the nebular theory include other ice rich planets, similar in size with Mars in a star, a terrestrial planet having a moon as large as earth’s moon.
Among those inconsistent with this theory are planets which do not orbit in the same plane because the planets in Solar systems orbit in almost the same plane .
