Existance of comets and asteroids
Planets orbit in the same direction and plane
Number of planets of each type (4 terrestrial and 4 jovian)
Which of the following statements is correct?
a. The formation of planets stopped because the solar nebula got cooler
c. The formation of planets stopped because the solar nebula ran out of planetesimals
d. The formation of planets stopped because the solar nebula spinning was slowing down
e. The formation of planets stopped because the young Sun's strong solar wind swept away material not yet accreted onto the planets
How do the planets in our solar system, for example Jupiter, affect the orbits of the other planets? How relatively stable are the orbits of the planets in the solar system?

Venus, because it is the warmest planet and so is more likely to be gaseous B. Mercury, because planets closer to the solar nebula are more likely to be made of gas, like the nebula C. Earth, because the atmosphere consists of nitrogen, oxygen, and other gases, so it is a gaseous planet D.
