Earth has a diameter of about 12,700 km.
Which is the 3 largest planet?
- Jupiter is the largest planet in the Solar System.
- Saturn is the second-largest planet, with a large and bright ring system.

- Neptune is the fourth-largest planet, as smallest of the four outer planets, but third-most massive.
Is Earth the 5th largest planet in the solar system?
Earth is the fifth largest of the planets in the solar system. It’s smaller than the four gas giants —Jupiter, Saturn, Uranus and Neptune — but larger than the three other rocky planets, Mercury, Mars and Venus.

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.
Is Jupiter bigger than Earth?
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.
Why is Earth called a unique planet?
Earth is the only planet in our solar system that has a large amount of liquid water. About 74% of the surface of Earth is covered by liquid or frozen water. Because of this, people sometimes call it “blue planet”. Because of its water, Earth is home to millions of species of plants and animals.
Are there 12 planets?
 The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Is Earth a planet?
Earth is the densest planet in the Solar System and the largest of the four terrestrial planets. Earth’s lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth’s surface is covered with water, mostly by oceans.
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.
How was earth named?
Etymology. Unlike the other planets in the Solar System, in English, Earth does not directly share a name with an ancient Roman deity. The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil. It became eorthe later, and then erthe in Middle English.
Does Europa have life?
So far, there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth’s deep-ocean hydrothermal vents.
Is the sun the biggest planet in the universe?
The extreme red hypergiant star VY Canis Majoris compared to the Sun and Earth’s orbit.
What lies in between Mars and Jupiter?
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
Is Pluto still 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.
What astronomical bodies are smaller than Earth?
Which is the smallest planet in our solar system?
Is Jupiter bigger than the moon?
Ganymede exceeds even the planet Mercury in diameter. They are respectively the fourth-, sixth-, first-, and third-largest natural satellites in the Solar System, containing approximately 99.997% of the total mass in orbit around Jupiter, while Jupiter is almost 5,000 times more massive than the Galilean moons.
Does Jupiter have an atmosphere?
The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water.
What is the size of Jupiter?
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.
How many planets have been discovered?
The first scientific detection of an exoplanet was in 1988; it was confirmed to be an exoplanet in 2012. The first confirmed detection occurred in 1992. As of 1 May 2019, there are 4,058 confirmed planets in 3,033 systems, with 658 systems having more than one planet. There are many methods of detecting exoplanets.
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 planet is in front of Earth?
On December 21, 2012, the Cassini–Huygens probe, in orbit around Saturn, observed the planet Venus transiting the Sun. On 3 June 2014, the Mars rover Curiosity observed the planet Mercury transiting the Sun, marking the first time a planetary transit has been observed from a celestial body besides Earth.
What type of planet is Earth?
A terrestrial planet, telluric planet, or rocky planet is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars.
How was Earth created?
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
How many moons does Pluto have 2018?
Does Pluto have an atmosphere?
The atmosphere of Pluto is the tenuous layer of gases surrounding Pluto. It consists mainly of nitrogen (N2), with minor amounts of methane (CH4) and carbon monoxide (CO), all of which are vaporized from their ices on Pluto’s surface.
How old is Pluto the dog?
Origin. Pluto first appeared as a nameless bloodhound tracking the escaped convict Mickey in the film The Chain Gang (September 1930). A month and a half later, Pluto appeared as Minnie Mouse’s dog named Rover who comes along with her and Mickey on a picnic.
