Jupiter, Saturn, & Neptune.
The inner planets are rocky, with distinct solid surfaces, and dense, whereas the outer planets are gaseous, have no solid surface and are relatively light in comparison. The density of Saturn, for example, is less than that of water.
Compared to the outer planets (gas giants), the four inner planets are small, have a greater average density, and receive most of their heat from the Sun. Mercury, Venus, Earth, and Mars are compact rocky planets, with a solid surface rather than a thick atmosphere. Their masses give them less gravity, but they contain a greater percentage of heavy elements, such as iron and zinc, than the larger planets. Without the Sun's radiation, their surfaces would be considerably cooler, as can be seen by the lower temperatures on Mars compared to Mercury and Venus.
Some planets with three moons include Neptune, Uranus, and Jupiter. These moons vary in size and characteristics, with some being relatively small and others having unique features such as volcanoes or subsurface oceans. Moons play a crucial role in shaping a planet's environment and gravitational dynamics.
In our solar system, the three planets that are generally visible to the naked eye in the night sky are Venus, Mars, and Jupiter. These planets can often be seen without the aid of a telescope or binoculars.
The three coldest planets in our solar system are Uranus, Neptune, and Pluto. These planets are located far from the Sun, resulting in extremely low temperatures that can reach as low as -224°C on Uranus, -214°C on Neptune, and -229°C on Pluto.

The three outer planets in our solar system are Jupiter, Saturn, and Uranus. These planets are located beyond the asteroid belt and are known for their large size, ring systems, and gaseous compositions.
The inner planets are rocky, with distinct solid surfaces, and dense, whereas the outer planets are gaseous, have no solid surface and are relatively light in comparison. The density of Saturn, for example, is less than that of water.
Mercury, Venus, and Earth are known as terrestrial planets because they are composed primarily of silicate rocks and metals, giving them high density compared to the gas giants in the outer Solar System.
A gas giant (sometimes also known as a Jovian planet after the planet Jupiter, or giant planet) is a large planet that is not primarily composed of solid matter. There are four gas giants in the Solar System: Jupiter, Saturn, Uranus, and Neptune.
Inner planets are rocky and terrestrial, while outer planets are gas giants. Inner planets are smaller in size and have solid surfaces, while outer planets are larger and lack a solid surface. Inner planets have shorter orbital periods and are closer to the sun, while outer planets have longer orbital periods and are farther from the sun.
Rock.
The three primary substances that make up the planets are gases, metals, and ices. Gaseous planets, like Jupiter and Saturn, are predominantly composed of hydrogen and helium, while terrestrial planets like Earth and Mars are mainly made up of silicate rocks and metals. Ices, such as water, ammonia, and methane, are also significant in the composition of some outer planets and their moons. The specific proportions of these substances vary, leading to the diversity of planetary types in our solar system.
