What is the real diameter of Mercury?
3,030 miles Mercury's diameter is 3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter's moon Ganymede and Saturn's moon Titan.

What is the diameter of Mercury for kids?
Size and Comparison We know that Mercury is the smallest planet. It has a radius of 2.439 km / 1.516 mi and a diameter of 4.879 km / 3.032 mi. But how does it compare to the other planets in the Solar System?
Which is bigger Mercury or Pluto?
In case you're wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto's equatorial diameter is just 2,302 km, about half Mercury's width.
Can we land on Mercury?
Could humans land on Mercury's surface? In spite of being so close to the Sun, and wild swings in extreme temperatures, humans could technically walk on the planet's surface. Mercury's slow rotation means it takes 59 Earth days for it to turn around once.
Does it rain diamonds on Jupiter?
New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. In fact the planets have the capability to create 1000 tonnes of diamonds a year.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.

What is the biggest planet ever found?
The largest planet ever discovered is called ROXs 42Bb, a planet with 2.5 times the radius of Jupiter. This exoplanet was directly imaged and discovered in 2013. Unlike many of the other largest exoplanets, this one is believed to be a planet and not a brown dwarf, an object between a planet and a star.
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.
Does diamonds rain on Jupiter?
But in the dense atmospheres of planets like Jupiter and Saturn, whose massive size generates enormous amounts of gravity, crazy amounts of pressure and heat can squeeze carbon in mid-air — and make it rain diamonds.
Why can’t astronauts go to Venus?
Venus is not easy to visit. Its carbon-dioxide-rich atmosphere is 90 times as dense as ours, and surface temperatures average 800 degrees Fahrenheit. Its surface pressure is intense enough to crush some submarines. But that hasn't stopped human space programs from trying.
What planet has acid rain?
planet Venus The most acidic rain in the Solar System is found on the planet Venus, where the working fluid in the cycle of evaporation, condensation and precipitation is a sulphuric acid solution (rather than water, as on Earth).
What rains on Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
What planet is the hottest?
Venus It has a strong greenhouse effect, similar to the one we experience on Earth. Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C!

Does Earth have 3 moons?

Can gold float in mercury?
It can also float liquids and gases that are less dense than mercury. Provided that gold sinks into mercury, This means that the mercury level is about $13$ times higher than that of water. Some artefacts, including pieces of lead, silver and steel, that sink in water will therefore float on mercury.
What happens if you swim in a pool of mercury?
Over time, the symptoms of mercury poisoning would include speech difficulties, lack of coordination, and even vision loss. And if you didn't manage to get out of the pool, you would surely pass out and die from metal's fumes.
Which planet is most like Earth?
Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
What planet is hottest?

What planets can humans live on?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
What is diamond rain?
The long chains then squeeze together to form crystalline patterns like diamonds. The dense diamond formations then drop through the layers of the mantle until it gets too hot, where they vaporize and float back up and repeat the cycle — hence the term "diamond rain."
