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 made Mercury not a livable planet?
Mercury's surface temperature reaches a scorching 430 degrees Celsius (800 degrees Fahrenheit) during the daytime, and in the absence of an atmosphere, it plummets to -180 degrees Celsius (-290 F) at night. So, its surface environments have rightfully been out of scientific consideration as a possible host of life.
Which planet is closest to Earth right now?
Mercury It's Mercury! Of all the planets in the Solar System, Mercury has the smallest orbit.
What planets have we not explored?
Out of the five planets known since ancient times as the 'wandering stars', Mercury is the one least explored. Unlike Venus, Mars, Jupiter and Saturn, Mercury is notoriously difficult to observe from Earth.
Has anyone went to Pluto?
The only spacecraft to visit Pluto is NASA's New Horizons, which passed close by in July 2015.
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 human landed on?

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.
Did Venus ever have life?
The possibility of life on Venus is a subject of interest in astrobiology due to Venus's proximity and similarities to Earth. To date, no definitive evidence has been found of past or present life there.
Was Venus once habitable?
Knoll light factory. Adobe After Effects CC 2017. Venus, our vexing sister planet, was likely habitable up to 900 million years after its formation, all without the need for plate tectonics (the global geological recycling of a planet's carbon).
How many years will it take to get to Mars?
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
Which planet has the coldest atmosphere?
Uranus holds the record for the coldest temperature ever measured in the solar system: a very chilly minus 371 degrees Fahrenheit (minus 224 degrees Celsius), according to NASA (opens in new tab) .
Is there another Earth with humans?

What planet can we live on besides Earth?
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.
Can we land on Uranus?
Surface. As an ice giant, Uranus doesn't have a true surface. The planet is mostly swirling fluids. While a spacecraft would have nowhere to land on Uranus, it wouldn't be able to fly through its atmosphere unscathed either.
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 planet has tornadoes?
Rather unusually, Mercury has magnetic 'tornadoes' that were observed by NASA's Mercury MESSENGER during a flyby in 2008. The tornadoes are twisted bundles of magnetic fields that connect Mercury's magnetic field to Space.
Does it snow in Mars?
Precipitation comes as powerful storms, not gentle drifts, on the Red Planet. Mars has surprisingly powerful snowstorms, which form at night. Although the planet has relatively little water vapour in its atmosphere, clouds of water-ice crystals can still develop.
