Quick Answer: Which Is The Second Largest Planet?

The biggest planet in the Solar System is Jupiter.

But the title for the second biggest planet in our Solar System goes to Saturn.

Just for a comparison, Jupiter measures 142,984 km across its equator.

Saturn for comparison is only 120,536.

Which planet is the most 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.

Is Earth the second largest planet in the solar system?

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.

What is the order of the planets from smallest to largest?

Originally Answered: What is the order of the planets from the smallest to the largest? Well, they start from the smallest one, in this case Mercury , then they go to the next, Mars, followed by Venus, Earth, Neptune, Uranus, Saturn and finally end with the biggest one, Jupiter.

What is the heaviest planet in the universe?

Whats bigger solar system or galaxy?

You are one of the billions of people on our Earth. Our Earth orbits the Sun in our Solar System. Our Sun is one star among the billions in the Milky Way Galaxy. Our Milky Way Galaxy is one among the billions of galaxies in our Universe.

What planets are bigger than Earth?

The Latest

  1. Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon.
  2. Venus. Venus spins slowly in the opposite direction from most planets.
  3. Earth.
  4. Mars.
  5. Jupiter.
  6. Saturn.
  7. Uranus.
  8. Neptune.

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.

Is Earth the 6th largest planet?

While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.

What is the hottest planet in our solar system?

Venus is the hottest world in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth. As a result, temperatures on Venus reach 870 degrees Fahrenheit (465 degrees Celsius), more than hot enough to melt lead.

Does Venus have a stronger gravity than Earth?

Since Venus and Earth are almost the same size and have about the same mass, the surface gravity on Venus is almost the same as the surface gravity on Earth. The surface gravity on Venus is about 91% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 91 pounds on Venus.

Are there 12 planets?

[1] The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

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.

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 Jupiter the largest planet in the universe?

The sizes are listed in units of Jupiter radii ( R J, R ♃)(71,492km). All planets listed are larger than two times the size of the largest planet in the Solar System, Jupiter.

Is 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.

Is a galaxy smaller than a universe?

Despite the prominence of large elliptical and spiral galaxies, most galaxies in the Universe are dwarf galaxies. These galaxies are relatively small when compared with other galactic formations, being about one hundredth the size of the Milky Way, containing only a few billion stars.

Is a light year larger than an astronomical unit?

The light-year is a unit of length used to express astronomical distances and measures about 9.46 trillion kilometres (9.46 x 1012 km) or 5.88 trillion miles (5.88 x 1012 mi).

What kind of galaxy is the Milky Way?


What planets have been visited by humans?


  • Mercury.
  • Venus.
  • Mars.
  • Jupiter.
  • Saturn.
  • Earth’s Moon.
  • Moons of Mars.
  • Moons of Saturn.

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 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 hotter than Mars?

Although Mars is smaller than the Earth, at 11% of Earth’s mass, and 50% farther from the Sun than the Earth, its climate has important similarities, such as the presence of polar ice caps, seasonal changes and observable weather patterns. It has attracted sustained study from planetologists and climatologists.

Is Venus hotter than Earth?

The fact that Venus is located closer to the Sun than Earth, raising temperatures on the surface to nearly 735 K (462 °C; 863 °F), the atmospheric pressure is ninety times that of Earth, and the extreme impact of the greenhouse effect, make water-based life as currently known unlikely.

Does Mars have water?

Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere, and occasionally as low-volume liquid brines in shallow Martian soil. The only place where water ice is visible at the surface is at the north polar ice cap.

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.

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.

How big is Jupiter?

69,911 km
