1) gas giants/outer planets: Jupiter, Saturn, Uranus Neptune; outside of the asteroid belt
2) Terrestrial planets/inner planets: Mercury, Venus, Earth, Mars; inside the asteroid belt
Terrestrial planets are like Earth, Mars, or Venus--they are smaller rocky masses that may also have a thin atmosphere.
Gas planets are like Jupiter, Saturn, or Uranus--they are larger masses that are composed primarily if not exclusively of matter in gas or liquid form.

∙ 12y agoThere are two main categorizations of planets, terrestrial planets and gas giants. These can be further subdivided to large terrestrial planets and dwarf planets, and gas giants and ice giants.
Planets are classified according to their composition. Terrestrial planets are mostly rock, metal, and some liquids. Gas giants are mostly gases (especially hydrogen, nitrogen, and helium).
In the solar system orbiting our sun, Sol, there are 18 recognized planets, with two protoplanets and thousands of asteroids and moons (some of which are larger than some of the dwarf planets). The planet classes in our system are as follows (ordered primarily by category and secondarily by mean orbital radius):
Dwarf Planets
- Ceres (5)
- Orcus (10)
- Pluto (11)
- Charon (12)
- Haumea (13)
- Quaoar (14)
- Makemake (15)
- "Snow White" (2007 OR10) (16)
- Eris (17)
- Sedna (18)
Terrestrial Planets
- Mercury (1)
- Venus (2)
- Earth (3)
- Mars (4)
Gas Giants
- Jupiter (6)
- Saturn (7)
Ice Giants
- Uranus (8)
- Neptune (9)
Protoplanets (honorable mentions)
- Vesta (5.3)
- Pallas (5.7)
It is interest to note that every dwarf planet in our system except Sedna orbits within one of our three asteroid belts (Asteroid Belt, 1, Kuiper Belt, 8, Oort Cloud, 0).

Do the densities of the solar system planets fall into two or more groups?
do the densities of the solar system planets fall into two or more groups
What are the two major groups that planets are divided?
Inner rocky planets and outer gas giant planets. (There are also Ice giants and dwarf planets)
How do the planets in the two groups different?
The first 4 planets, Mercury, Venus, Earth, and Mars, are called rock planets, and the last 4, Jupiter, Saturn, Uranus, and Neptune, are the gas planets. The main differences between these two groups are that the rock planets are made of rock, the gas planets are made of gas, the rock planets are typically smaller than the gas planets, and the gas planets have rings.
What are the inner planets and the outer planets and how do the planets in the two groups differ?
The inner planets are Mercury, Venus, Earth and Mars. The outer planets (they are separated by the asteroid belt) are Jupiter, Saturn, Uranus, and Neptune. The outer planets are different than the inner planets because the outer planets are not solid. They are all made up of gas. However, the inner planets are rocky and hard.
What are the 2 groups that divide the periodic table and their properties?
Metals and non-metals are the two groups. Metal loose electrons. Non metals gain electrons.
What is another way you might divide the planets into two groups other than the inner planets and the outter planets?
Stony and Gas Giant. But it still divides the same.
Do the densities of the solar system planets fall into two or more groups?

Can 366 divide into groups of 2?
183
What two major groups are the planets broken into?
There aren't really two groups but All the planets before the asteroid belt (mercury Venus Mars and earth) are rocky planets and all the planets after the asteroid belt (Jupiter Saturn Uranus and Neptune) are gas giants.
What are the two major groups that planets are divided?
Inner rocky planets and outer gas giant planets. (There are also Ice giants and dwarf planets)
Can ordinary shares divide into two groups?
it depends

How can you divide 28 cans of soda into two groups so that the ratio is 3 to 4?
Divide 28 cans of soda into two groups so the ratio is 3 to 4
What two groups did Aristotle divide animals into?
He divided animals into two groups- those with red blood and those without it.
What are the two planet groups?
There are the inner, terrestrial planets, also know as the rocky planets. Earth is one of these. Then there are the outer planets, also know as the gas planets or gas giants.
Scientist divide vertebrates into two main groups agree or disagree?
no
What does subdivided mean in math?
To divide something that has already been divided. 8, which can be divided into two groups of four, can be subdivided into four groups of two.
