What planets have oceans?
In 2015, NASA confirmed that liquid water flows intermittently on present-day Mars. Also in 2015, scientists used data from NASA’s Cassini mission to discover that a global ocean lies beneath the icy crust of Saturn’s moon Enceladus. Scientists believe that Jupiter’s moon Europa has a subsurface ocean as well.
Can mercury support water?
Short answer: Yes, Mercury has some frozen water (ice). Long answer: Mercury is the closest planet to the Sun so you might expect it to be far too hot to have any water. However Mercury also has some very cold areas that are able to support frozen water (ice).
Can you live on Mercury?
No evidence for life has been found on Mercury. Daytime Temperatures can reach 430 degrees Celsius (800 degrees Fahrenheit) and drop to -180 degrees Celsius (-290 degrees Fahrenheit) at night. It is unlikely life (as we know it) could survive on this planet.
Does Mercury have water or ice on it?
Mercury is not alone in having ice on its surface, as water ice has also been discovered on the moon and on small worlds such as asteroids and comets. These locations may have variations in water deposition, however.
Is Mercury too hot for water to exist?
Recent data show that water ice may exist in the bottoms of craters at Mercury’s poles. Although Mercury is the closest planet to the Sun, and can be extremely hot over most of its surface, ice may exist at the bottoms of some polar craters because the crater floors are permanently shadowed by the crater rims.
Does Mercury have a night?
It takes about 176 Earth days for Mercury to rotate on its axis (from sunrise to sunrise), while Earth takes only 24 hours. On Mercury, it is daytime for one year, and night for one year.
How old would I be on Mercury?
4.503 billion years
Does it get dark on Mercury?
Mercury’s bleak, airless surface is similar to the moon’s, so scientists have long been puzzled why the planet reflects so much less light than our lunar satellite. That’s because Mercury’s brightness at one particular wavelength suggests that there’s less than 3% iron in its surface rocks. …
How cold is Mercury at night?
Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
Which planet is always in the dark?
The planet known as TrES-2b sounds like it should glow like wild. It’s only about three million miles from its parent star — much closer than Mercury is to the Sun. And its night side may sizzle at almost 3,000 degrees. Yet the planet appears to be the darkest yet seen — darker than charcoal.

Which is the darkest planet in the universe?
Kepler has found the darkest known planet in universe–a Jupiter-sized exoplanet some 750 light-years away that is so black that it reflects just one percent of the light that reaches it. TrES-2b is so black that it’s darker than coal, or any other planet or moon that we’ve yet discovered.
