The outer planets are further away, larger and made up mostly of gas.
The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.
Which is the largest of the inner planets?
- Mercury. Mercury is the innermost planet and is also the smallest planet of our solar system. It is only slightly larger than Earth’s Moon.
- Venus. Venus is the second planet from the sun.
- Earth. Next is our home planet, Earth.
- Mars. Mars is the fourth and last of the inner planets.
What planet is the biggest?
Largest Planet: Jupiter. The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.

What are the 4 inner planets?
The four innermost planets in the Solar System (Mercury, Venus, Earth, and Mars) are sometimes called the “terrestrial” planets because of their proximity to Earth (“Terra” in Latin) and their similarity as compact solid bodies with rocky surfaces.
What planet is bigger than the sun?
Big, Bigger, Biggest. Although the Sun looks small from Earth, it is really much, much bigger than our planet (and any other planet in the solar system). The Earth is actually one of the smaller planets compared to the giant planets in the outer solar system – Jupiter, Saturn, Uranus, and Neptune.
Are there 12 planets?
 The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
What’s the biggest planet in the galaxy?
What planets are bigger than Earth?
- Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon.
- Venus. Venus spins slowly in the opposite direction from most planets.
What is the biggest planet known to man?
What’s The Largest Planet In The Universe?
- The exoplanet Kepler-39b is one of the most massive ones known, at 18 times the mass of Jupiter, placing it right on the border between planet and brown dwarf.
- A cutaway of Jupiter’s interior.
- WASP-17b is one of the largest planets confirmed not to be a brown dwarf.
Is Earth the only inner planet with a moon?
Of the inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos.
Which planet is bigger Uranus or Neptune?
Neptune is the eighth planet from the Sun and the fourth largest (by diameter). Neptune is smaller in diameter but larger in mass than Uranus.
How many planets are smaller than Earth?
Two of them are smaller than Earth, and one of these is smaller than Mercury, the smallest of the eight planets in Earth’s solar system. Until now, astronomers had never found a planet smaller than Mercury.
Which planet is most like Earth in size?
What are the first four planets called?
There are eight planets in the Solar System. From closest to farthest from the Sun, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The first four planets are called terrestrial planets.
Why are gas giants called gas giants?
A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System.
Is there any planet bigger than Jupiter?
All planets listed are larger than two times the size of the largest planet in the Solar System, Jupiter. Some planets that are smaller than 1.7 R J have been included for comparison.
Is Jupiter as big as the sun?
Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.
Is Saturn bigger than the sun?
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It has only one-eighth the average density of Earth, but with its larger volume Saturn is over 95 times more massive.
Is there a 10th planet?
With the exception of some long-period comets, until 2018 VG18 was discovered on December 17, 2018, Eris and Dysnomia were the most distant known natural objects in the Solar System. Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System’s tenth planet.
Why Pluto is not a planet?
In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term “planet” formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.
Is the sun a planet?
The Sun is the Solar System’s star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium, making it a main-sequence star.
What is the largest non gas planet?
In May 2014, previously discovered Kepler-10c was determined to have the mass comparable to Neptune (17 Earth masses). With the radius of 2.35, it is currently the largest known planet likely to have a predominantly rocky composition.
Is Kepler 22b habitable?
Kepler-22b, also known by its Kepler object of interest designation KOI-087.01, is an extrasolar planet orbiting within the empirical habitable zone of the Sun-like star Kepler-22. It is located about 587 light-years (180 pc) from Earth in the constellation of Cygnus.
Is the Earth the largest planet?
Jupiter is the largest planet in the Solar System. It has four very large satellites (moons). Saturn is the second-largest planet, with a large and bright ring system. Uranus is the third-largest planet and the least massive of the four outer planets.
Is the moon larger than Earth?
The Moon is exceptionally large relative to Earth: Its diameter is more than a quarter and its mass is 1/81 of Earth’s. It is the largest moon in the Solar System relative to the size of its planet, though Charon is larger relative to the dwarf planet Pluto, at 1/9 Pluto’s mass.
Is Earth bigger than Mars?
Mars is approximately half the diameter of Earth, with a surface area only slightly less than the total area of Earth’s dry land. Mars is less dense than Earth, having about 15% of Earth’s volume and 11% of Earth’s mass, resulting in about 38% of Earth’s surface gravity.
What astronomical bodies are smaller than Earth?
