The coldest
Though not too distant from its host star at an orbit that would put it somewhere between Mars and Jupiter in our solar system, its host star is a low mass, cool star known as a red dwarf.
The planet is popularly referred to as Hoth in reference to an icy planet in the Star Wars franchise.
What is the coldest planet in the universe?
It depends upon how you define “coldest.” With Pluto out of the race, the farthest “real” planet from the Sun is Neptune. Neptune and its neighbor, Uranus, are known as the “ice giants,” since they are composed of huge amounts of rock and water, ammonia, and methane ice crystals.
What is the biggest planet ever recorded?
Jupiter
What is the farthest planet ever discovered?
The most distant potentially habitable planet confirmed is Kepler-443b, at 2,540 light-years distant, although the unconfirmed planet KOI-5889.01 is over 5,000 light-years distant. Also the closest rocky exoplanet, and closest potentially habitable exoplanet known.
What planet came first?
Five planets have been known since ancient times — Mercury, Venus, Mars, Jupiter, and Saturn. The first new planet discovered was Uranus. It was discovered by the English astronomer Sir William Herschel in 1781. Herschel was one of the first modern astronomers.
What is an interesting fact about Uranus?
While being visible to the naked eye, it was not recognised as a planet due to its dimness and slow orbit. Uranus became the first planet discovered with the use of a telescope. Uranus is tipped over on its side with an axial tilt of 98 degrees. It is often described as “rolling around the Sun on its side.”
What would it be like to live on Uranus?
The first is the fact that Uranus has no solid surface. It’s mostly composed of ices: methane, water and ammonia. And then it’s enshrouded by an atmosphere of hydrogen and helium. Life on Uranus would have to be vastly different from anything we have here on Earth to be able to survive.
What is the most dangerous planet?
If you have seen the giant swirling hurricanes photographed by the Juno spacecraft flying over Jupiter’s poles, the largest planet in our solar system is certainly a good contender. However, the title goes to Venus. A planet the same size of Earth, it is shrouded in clouds of sulfuric acid.
What is the smallest planet ever discovered?
The discovery of a strange new world about the size of Earth’s moon has shattered the record for the smallest known alien planet, scientists say. The newfound alien planet Kepler-37b is the first exoplanet discovered to be smaller than Mercury.

What is the farthest object ever seen in the universe?
This close-up view shows the galaxy MACS0647-JD, the farthest object yet known, as it appears through a gravitational lens imaged by the Hubble Space Telescope. The galaxy is 13.3 billion light-years from Earth and formed 420 million years after the Big Bang.
How long would it take to get to Pluto from Earth?
9.5 years
What is the new planet called 2018?
A new dwarf planet called Farout is the most distant we’ve ever seen. There’s a new dwarf planet in our solar system, and it’s the most distant one we’ve ever discovered. The tiny world, formally known as 2018 VG18 but nicknamed Farout, is about 18 billion kilometres away – roughly 3.5 times the distance to Pluto.
What is the oldest planet in the universe?
Long before our Sun and Earth ever existed, a Jupiter-sized planet formed around a sun-like star. Now, 13 billion years later, NASA’s Hubble Space Telescope has precisely measured the mass of this farthest and oldest known planet.
What’s the oldest planet in the solar system?
The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old.

What was the first planet discovered by telescope?
Uranus
Who named Uranus?
Astronomers decided to continue naming the planets after Roman Gods with one exception – Uranus. Uranus was named after the Greek god of the sky. According to myth, he was the father of Saturn and the grandfather of Jupiter.
How does Uranus get its color?
Uranus’ atmosphere is made up of hydrogen, helium and methane. The methane in Uranus’ upper atmosphere absorbs the red light from the Sun but reflects the blue light from the Sun back into space. This is why Uranus appears blue.
Does it rain diamonds on Uranus?
High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune, while some planets in other solar systems may be almost pure diamond. Diamonds are also found in stars and may have been the first mineral ever to have formed.
Can humans breathe on Europa?
Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. From the surface of Europa, Jupiter appears 24 times larger than the moon appears in our sky. Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.
Is it possible to live on the moon?
Really, you would have to definitely live in caves on the moon, but on Mars, it might be possible to live above-ground. You would still get a fair bit of radiation exposure, though.
Can we live on Pluto?
It is only half as wide as the United States. Pluto is smaller than Earth’s moon. This dwarf planet takes 248 Earth years to go around the sun. If you lived on Pluto, you would have to wait 248 Earth years to celebrate your first birthday.
Has Saturn explored?
In 1979, Pioneer 11 became the first spacecraft to fly by and study Saturn up close. Voyager 1 flew by in 1980 and Voyager 2 in 1981. These spacecraft studied many of the moons of Saturn as well. In July 2004, the Cassini spacecraft reached Saturn.
Will Pluto ever crash into Neptune?
Pluto and Neptune orbits are not in the same plane. Jason asks: “Since Pluto’s orbit intersects Neptune’s orbit, will Pluto ever crash into Neptune or become one of Neptune’s moons?” Answer: No. From 1979 to 1999, Pluto was the eighth planet from the sun.
Why is the Earth tilted at 23 degrees?
Instead, Earth has seasons because our planet’s axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth’s orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.
Was Neptune the last planet discovered?
September 23, 1846. The planet Neptune – now considered by most astronomers to be the outermost major planet in our solar system – was discovered on this date, using mathematics. Its discovery didn’t come solely through the use of a telescope, though. It came from astronomers’ analysis of data related to Uranus’ orbit.
Who named the planets?
The tradition of naming the planets after Greek and Roman gods and goddesses was carried on for the other planets discovered as well. Mercury was named after the Roman god of travel. Venus was named after the Roman goddess of love and beauty. Mars was the Roman god of War.
Who discovered the planet Earth?
Three planets required good telescopes for their discovery: Uranus was discovered by Sir William Herschel in 1781. Herschel was probably the most famous astronomer of the 18th century. In addition to discovering the planet Uranus, he also observed and cataloged over 800 double stars and 2,500 nebulae.
Does it rain diamonds on Pluto?
‘Diamond rain’ falls on Saturn and Jupiter. Diamonds big enough to be worn by Hollywood film stars could be raining down on Saturn and Jupiter, US scientists have calculated. New atmospheric data for the gas giants indicates that carbon is abundant in its dazzling crystal form, they say.
Why does it rain diamonds on Neptune?
It rains solid diamonds on Uranus and Neptune. Consider this your daily reminder that the solar system is even more awesomely bonkers than you realized: On Uranus and Neptune, scientists forecast rain storms of solid diamonds. The gems form in the hydrocarbon-rich oceans of slush that swath the gas giants’ solid cores.
Is there gold on the moon?
There is water on the moon … along with a long list of other compounds, including, mercury, gold and silver. That’s according to a more detailed analysis of the chilled lunar soil near the moon’s South Pole, released as six papers by a large team of scientists in the journal, Science Thursday.
