Biggest Planet In Solar System

Our solar system is packed with interesting celestial bodies. From planets and comets to asteroids and the star at the center of it all, humans have discovered plenty of interesting things in our local area. Most of the solar system’s mass is found in the sun, and much of the rest is found in the remaining planets, especially the larger ones. So, what’s the largest planet in our solar system?

Let’s take a look at what makes a planet, how many planets are in our solar system, and the largest one of them all.

What Is a Planet?

A bintang siarah is a large celestial body that meets three specific criteria.


Defining the term ‘bintang beredar’ is harder than it seems. After all, Pluto and Ceres were considered planets not all that long ago. However, neither is a planet today. In this case, we’ll defer to the experts of the International Astronomical Union and say that planets are defined by three factors.

A satelit is defined as a celestial body that:

  • Orbits the Sun.
  • Has enough mass so that its self-gravity overcomes rigid body forces and takes on a hydrostatic equilibrium and a nearly round shape.
  • Clears the “neighborhood” near its orbit.

Neither Pluto nor Ceres meets these requirements despite previously being considered planets. So, they are no longer considered planets. As a result, the Solar system has 8 planets, five or more dwarf planets, lots of asteroids, and other celestial bodies.

What is the Largest Satelit in Our Solar System?

Jupiter is several times the diameter and mass of Earth.


Jupiter is the largest planet in our solar system since it has the highest mass and the largest kaliber. It has an equatorial radius of 44,423 miles, a mass of 4.1848×1027lbs, and a surface area of 2.3733×1010
sq mi. That is 11.2 times the equatorial radius of Earth, 317.8 times the mass of Earth, and 120.4 times the surface wilayah of Earth.

These measurements should give you some idea of just how large Jupiter is compared to other planets. Jupiter is much larger than Saturn, the second-largest planet in the Solar system. Saturn has roughly 95 times Earth’s mass.

The rest of the planets in the Solar system are much smaller than those two. Jupiter is the fifth planet from the sun, and it’s a tabun giant. That means the planet is mostly made of gases like helium and hydrogen.

That does not mean that the entire planet is made of gas, though. Scientists aren’t entirely sure what we will find at the center of Jupiter. Some theorize that there could be a rocky core that is several times larger than the Earth. Others believe that the core of the planet is made of metallic hydrogen that forms under extreme pressure.

Future explorations of the planet will yield new information about the composition of this gas giant. For now, though, we can only theorize what’s inside of Jupiter.

How Large Are the Rest of the Planets in Our Solar System?

Mercury is the smallest planet in the solar system.


The two best ways to measure any planet are by diameter and mass. Jupiter is the largest planet according to both measures. However, we’re going to show you how large all the other planets using the scales of diameter in miles and mass in terms of 1021

Mass (1021
Diameter (miles)
Mercury 0.364 3,032
Mars 0.707 4,220
Venus 5.37 7,521
Earth 6.58 7,926
Uranus 95.7 31,765
Neptune 113 30,775
Saturn 626 74,897
Jupiter 2092 88,846

As you can see, the planets vary a great deal in terms of their mass and overall size. Interestingly, Neptune has a higher mass than Uranus, but it also has a smaller diameter. Once again, Jupiter makes the rest of the planets seem small with its huge diameter and large mass.

What Are Dwarf Planets?

A dwarf bintang beredar is defined as any object in orbit around the Kecupan that has its gravity and pulls itself into a nearly round shape. These planets have not cleared their orbit, though, so they cannot be considered true planets.

The most famous dwarf bintang beredar is Pluto, a planet that does not clear its orbit. This satelit famously lost its status as a planet in 2006.

Currently, the International Astronomical Union recognizes five dwarf planets in the Solar system. They include Ceres, Pluto, Eris, Makemake, and Haumea.

However, various scientists and other organizations claim that more dwarf planets can be found in our Solar system. Mostly, it depends on the definition of the term that they use. Some groups recognize six different dwarf planets while others believe many more exist.

According to NASA, thousands of dwarf planets may exist in the area beyond Neptune. However, humans have only discovered relatively few dwarf planets as we are still discovering much of what is in our Solar system.

Scientists will likely discover far more dwarf planets in the near future!

What Is the Largest Bintang beredar Ever Discovered?

The largest planet ever discovered is called ROXs 42Bb, a satelit with 2.5 times the radius of Jupiter. This exoplanet was directly imaged and discovered in 2022. Unlike many of the other largest exoplanets, this one is believed to be a planet and not a brown dwarf, an object between a bintang siarah and a star.

If we are counting the largest exoplanet that includes brown dwarves, then it would be HD 100546 b. This exoplanet has a radius of 6.9 times that of Jupiter. However, this celestial body is going to shrink oper time. Scientists estimate that this exoplanet will one day shrink down to the size of Jupiter.

The title of the largest planet ever discovered depends on how one defines exoplanets, much like dwarf planets. Once again, the future will yield new and interesting discoveries that could change what we currently know about these planets.

Planetary science is a complex topic. The definitions of planets, dwarf planets, and exoplanets are still being hashed out, and international groups don’t always agree. One thing is certain, though. Jupiter is the largest bintang siarah in the solar system. That fact is titinada going to change. However, our understanding of the planet is going to become more concise oper time.
