Compare and Contrast
From the table above, the Earth’s Moon and Mercury have similar
characteristics such as, not having an atmosphere. Another common trait is the craters that they both have. The result of not having any atmosphere prevents the asteroid from burning up. Not like Earth, Venus, and Mars that have an atmosphere and that asteroids end up burning up because of the heat that the atmosphere makes. The Earth’s Moon and Mercury also have a smaller mass than the rest of the terrestrial planets. If you want to learn more check out What is norepinephrine?
Terrestrial planets and Jovian planets
The large Jovian planets initially formed through a similar process as the terrestrial planets through the accretion of planetesimals.
The planets in our solar system have similar interiors composed of a core and a mantle.
Terrestrial and Jovian planets have weather Don't forget about the age old question of How can water form hydrogen bonds?
One of the differences is the surface of the terrestrial and Jovian
planets. While the terrestrial planets are made of solid surfaces, the
Jovian planets are made of gaseous surfaces.
Jovian planets are less dense when compared to the terrestrial planets, because they are mainly composed of hydrogen gas. We also discuss several other topics like What is the function of exponential random variables?

Don't forget about the age old question of What are the symptoms of hypoglycemia?
The core of the Jovian planets is denser than the terrestrial planets
the Jovian planets are much larger than the terrestrial planets
the Jovian planets have more moons than the terrestrial planets.
While the terrestrial planets spin less, the Jovian planets spin more,
and due to this fact, the terrestrial planets tend to be less flattened at
The terrestrial planets were much hotter when they were formed, and they cooled with time. The terrestrial planets were hit by meteorites during the early times, which made them so hot. This is why Earth and Venus have very hot interiors when compared to other planets.
Try to look at the table and see all differences and similarities for each. How and why are they like that?
