What is the 8 planet to the Sun?
Neptune: Neptune is the eighth and farthest planet from the Sun, at a distance of about 4.5 billion km (2.8 billion miles) or 30.07 AU. Like Jupiter, Saturn and Uranus, it is technically a gas giant, though it is more properly classified as an “ice giant” with Uranus.

Why Pluto is not a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Which is the smallest planet?
Mercury
Kid-Friendly Mercury
Mercury is the smallest planet in our solar system. It’s a little bigger than Earth’s Moon. It is the closest planet to the Sun, but it’s actually not the hottest.
Which is the hottest planet?
Venus
Venus is the second planet from the Sun and Earth’s closest planetary neighbor. Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid.
Is there a 10th planet?
Answer: There is no known Planet X or 10th planet in our solar system. Scientists have been looking for about a hundred years. It was believed that such a planet was required to explain the orbital characteristics of the outer planets Uranus and Neptune.
Which is the red planet?
Mars
Mars is known as the Red Planet. It is red because the soil looks like rusty iron. Mars has two small moons. Their names are Phobos (FOE-bohs) and Deimos (DEE-mohs).

Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
What is the hottest planet?
Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet.
What is biggest planet on Earth?
Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter’s stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.

Venus: Earth’s twin planet?
What planet is the coldest?
Uranus
The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and ‘only’ about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
What is Earth’s twin planet?
Venus is often called “Earth’s twin” because they’re similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
What is the oldest planet?
Jupiter formed in a geologic blink. Its rocky core coalesced less than a million years after the beginning of our solar system, scientists reported Monday in the Proceedings of the National Academy of Sciences.

Is Mars a dead planet?
The Red Planet is a dead planet, but it may not have always been that way. Rovers and satellites have found clear evidence that the dusty Martian plains once flowed with rivers, which pooled into giant lakes, and perhaps fed into a global ocean.
Will sun burn out?
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. One way or another, humanity may well be long gone by then.
How old is the Earth?
4.543 billion yearsEarth / Age
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
Why was Pluto removed?
How many Earths are in the universe?
There are a billion Earths in this galaxy, roughly speaking. Not a million. A billion. We’re talking 1 billion rocky planets that are approximately the size of the Earth and are orbiting familiar-looking yellow-sunshine stars in the orbital “habitable zone” where water could be liquid at the surface.
