What inner planets mean?
The inner planets, or terrestrial planets, are the four planets closest to the Sun: Mercury, Venus, Earth, and Mars. Figure below shows the relative sizes of these four inner planets.
What are 4 characteristics of the inner planets?
Summary
- The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal.
- The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings.
- The outer planets are made of hydrogen and helium, so they are called gas giants.
Which inner planet is the hottest?

Is Venus Earth’s sister?
Venus is very similar to Earth in size and mass – and so is sometimes referred to as Earth’s sister planet – but Venus has a quite different climate. Venus’ thick clouds and closeness to the Sun (only Mercury is closer) make it the hottest planet – much hotter than the Earth.
Do we have 2 suns?
So, if not for some cosmic event or quirk, Earth could have had two suns. But we don’t. They’re just really hard to find, since there are so many stars in the Milky Way, and the Sun’s siblings – as all stars do – have scattered widely. To date, only a few candidates for solar siblings have been identified.
Does Venus have ice?
Venus is too hot to have any type of ice on it. The surface of Venus is covered by its thick atmosphere of carbon dioxide. Water ice is found where the temperatures are below the freezing point of water and there is enough precipitation for snow or ice crystals to fall or there is water that can freeze.
Why Venus is hottest planet not Mercury?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
Is Pluto still a planet 2020?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
