Is Jupiter hot or cold?

The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit). The temperature near the planet's center is much, much hotter. The core temperature may be about 24,000 degrees Celsius (43,000 degrees Fahrenheit). That's hotter than the surface of the sun!

How was Pluto named?

Pluto was finally discovered in 1930 by Clyde Tombaugh at the Lowell Observatory, based on predictions by Lowell and other astronomers. Pluto got its name from 11-year-old Venetia Burney of Oxford, England, who suggested to her grandfather that the new world get its name from the Roman god of the underworld.

How was Charon discovered?

Charon was discovered in 1978 when sharp-eyed astronomer James Christy noticed images of Pluto were strangely elongated. Searching through their archives of Pluto images taken years before, Christy found more cases where Pluto appeared elongated.

Does Jupiter have volcanoes?

There are volcanoes all around our solar system. But only a few places besides Earth—like some of the moons of Jupiter, Saturn, and Neptune—have active ones today. Use the Space Volcano Explorer to learn more about our solar system's many volcanoes.

Is there any land on Jupiter?

Surface. As a gas giant, Jupiter doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either.

Is Jupiter a failed star?

"Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.

Which planets have been demoted from being a planet?

In our own solar system, most of the planets have always been visible to the naked eye and only the three furthest – Uranus, Neptune, and Pluto (which has been demoted from being a planet) – required strong telescopes to be discovered.

Which planet has the most moons?

As technology has advanced, scientists and astronomers have been able to observe planets beyond our solar system, which are known as exoplanets. Through their research, we now know the age of our own solar system as well as several notable exoplanets.

What is the surface of Mars?

The surface of Mars is covered with craters, volcanoes, and plains. The largest volcanoes of any planet are on Mars. Jupiter is a gas giant, so it has no solid surface just a core of liquid metals. Astronomers have created a definition for the surface – the point at which the atmosphere’s pressure is one bar.

Can life exist on other planets?

People have been intrigued for centuries by whether life could exist on other planets. While we now know that it is very unlikely that life as we know it could exist on other planets in our Solar System, many people do not know the surface conditions of these various planets. Mercury resembles nothing so much as a larger version of the Moon.

Does Mercury have life on other planets?

While we now know that it is very unlikely that life as we know it could exist on other planets in our Solar System, many people do not know the surface conditions of these various planets. Mercury resembles nothing so much as a larger version of the Moon.
