To put that in perspective, Jupiter diameter is roughly 11 times that of Earth, and 2.5 the mass of all the other planets in the Solar System combined.
But, being a gas giant, Jupiter has a relatively low density – 1.326 g/cm3 – which is less than one quarter of Earth’s.

Who are the member of Solar System?
Members of the solar system. 2. Solar System The solar system is made up of the sun, its planets, asteroids, meteoroids, and comets. Each of these bodies are held to each other by the force of gravity.
How many planets are in our solar system 2018?
The Current Official Answer : 8. The simple official answer to this question is 8. The solar system planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
What is the largest known non Planet object in the solar system?
1.) Ganymede: Jupiter’s largest moon is the largest non-planet in the Solar System. With a diameter of 5,268 km (3,271 miles), it’s 8% bigger than the planet Mercury, although it has less than half the mass of our Solar System’s innermost planet, being made of mostly ices and silicate minerals.
What is the largest thing in the solar system?
Eight known planets and their moons, along with comets, asteroids, and other space objects orbit the Sun. The Sun is the biggest object in our solar system. It contains more than 99% of the solar system’s mass.
Is the sun a planet Yes or no?
Shown in order from the Sun and in true color. Sizes are not to scale. A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.
What are the 12 planets?
If the proposed Resolution is passed, the 12 planet in our Solar System will be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313.
Why is Pluto no longer 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 Earth a star?
A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The nearest star to Earth is the Sun.
Are moons planets?
The Moon, also known as Luna, is an astronomical body that orbits planet Earth and is Earth’s only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).
Is the sun a planet or a star?
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.
How many planets exist in the universe?
On November 4, 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way galaxy. 11 billion of these estimated planets may be orbiting Sun-like stars.
How many planets have we 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.
How many galaxies are in the universe?
Several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to 2 trillion galaxies.
Why asteroids are not considered planets?
Larger asteroids have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not resemble a planet-like disc and was not observed to have characteristics of an active comet such as a tail.
Is Ceres bigger than the moon?
It was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet. Although it was still more than ten times as massive as the largest object in the asteroid belt, Ceres, it had one-fifth the mass of Earth’s Moon.
Is the sun bigger than Jupiter?
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.
How big is the Hercules Corona Borealis Great Wall?
The Hercules–Corona Borealis Great Wall is the largest known super-structure in the universe. It is a huge group of galaxies forming a giant sheet-like pattern. It is about 10 billion light-years long, 7.2 billion light-years wide, and almost 1 billion light-years thick.
What is smaller than a Preon?
Preon. In particle physics, preons are point particles, conceived of as subcomponents of quarks and leptons. The word was coined by Jogesh Pati and Abdus Salam in 1974.
What is bigger than a supercluster?
Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe. These are the largest known structures to date.
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.
What is the 11th planet from the sun?
Eleventh planet (of the Solar System) may refer to Vesta, the eleventh object to be named a planet, later to be reclassified as an asteroid; Uranus, the eleventh planet from the Sun upon Vesta’s discovery, though this was quickly superseded by new discoveries; or Haumea, which would be the eleventh planet if the
What determines a planet?
This definition, which applies only to the Solar System, states that a planet is a body that orbits the Sun, is massive enough for its own gravity to make it round, and has “cleared its neighbourhood” of smaller objects around its orbit.
Who named Pluto?
Venetia Katharine Douglas Burney
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.
