What are the 8 planet in order?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
Is Neptune the 8th largest planet?
Neptune is the eighth and outermost planet in our solar system. It is the fourth-largest planet by diameter and the third-largest by mass; Neptune is 17 times the mass of Earth and is slightly more massive than its near twin Uranus which is 14 Earth Masses, but slightly smaller due to its higher density.
What are the 12 planets in order?
If the resolution is approved, the 12 planets in our solar system listed in order of their proximity to the sun would be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and the provisionally named 2003 UB313.
Is Earth the 5th 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.
Is there 8 or 9 planets?

Why can’t humans live on Neptune?
To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That’s very cold, and there’s no way liquid water could exist.
Does it rain diamonds on Jupiter?
Thus, we can say that it literally rains diamonds on Saturn and Jupiter. But these diamonds do not stay in solid form for too long as when they move farther into the depths of the planets, the pressure and temperature there are strong enough to melt them into liquid, creating liquid diamonds.
Why is Jupiter so big?
How did the largest planet in our solar system form? The traditional view is that Jupiter first formed a rocky core, several times the size of Earth, which then attracted a still larger outer envelope of gas. This process is known as “accretion.”

What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
What is the most unique planet?
Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. It is not the only planet to have rings—made of chunks of ice and rock—but none are as spectacular or as complicated as Saturn’s. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium.
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.
Who made earth?
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.
What is the smallest planet on Earth?
The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth’s Moon.
