Tough Place for Life It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures.
Mercury has extreme climes. The part facing the sun is extremely hot, whereas the other side is freezing. There is a lack of air on this planet. Without a spacesuit, one would survive for hardly 2 minutes.
Most astronomers feel that it would be impossible for life to exist on Venus. Today, Venus is a very hostile place. It is a very dry planet with no evidence of water, its surface temperature is hot enough to melt lead, and its atmosphere is so thick that the air pressure on its surface is over 90 times that on Earth.
All evidence that science has do date indicates that there has never been life on Mercury and never will be. The harsh conditions on the planet's surface and the tenuous atmosphere make it impossible for any life form known to man to exist.
Challenges: Of course, a colony on Mercury would still be a huge challenge, both economically and technologically. The cost of establishing a colony anywhere on the planet would be tremendous, and would require abundant materials to be shipped from Earth, or mined on site.
Although usually disregarded as being too hot, Mercury may in fact be one of the easiest bodies in the solar system to terraform.
Mercury-P (Меркурий-П) is a proposed mission to Mercury by the Russian Space Agency. The currently anticipated launch date is 2031. It is planned to be a lander.
Flexi Says: Right now and for the foreseeable future, humans can only live on Earth. Humans have not traveled very far into space. The Moon is the only other place humans have visited. No other planet in our solar system currently has the conditions to support life as we know it on Earth.
As unlikely as it seems, a new study announced by researchers at the Planetary Science Institute (PSI) suggests that some regions in Mercury's subsurface might have once been hospitable enough for prebiotic chemistry or – perhaps – even simple microscopic lifeforms.
Saturn's environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Potential for Life
The surface of Pluto is extremely cold, so it seems unlikely that life could exist there. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like. Pluto's interior is warmer, however, and some think there could even be an ocean deep inside.
Jupiter cannot support life as we know it. But some of Jupiter's moons have oceans beneath their crusts that might support life.
Uranus' environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Kepler 452b is located in the constellation Cygnus. It is 1,400 light-years away from Earth. I would choose Kepler 452b over other habitable planets for several reasons. There are signs that its surface holds a water-like substance.
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.
Alan Shepard piloted the first crewed Mercury flight, Freedom 7, shown here a few seconds after launch [NASA Photograph]. Initiated in 1958 and completed in 1963, Project Mercury was the United States' first human-in-space program.
Humans attempting to visit Mercury would find a similar environment to the Moon. Mercury is airless, so they would need a spacesuit to protect themselves from the vacuum of space.
Io, Ganymede, and Europa all have oxygen in their atmospheres, and roaming could be the cause. Io is a volcanic place – the most volcanic world in the Solar System – so life is ruled out there. Ganymede and Europa have subsurface oceans, so they could potentially harbour life.
This planet, named TOI-700 e, falls within its star's habitable zone, meaning the newfound planet could be capable of supporting life as we know it. The research team announced the finding Jan. 10 at the American Astronomical Society meeting in Seattle.
Just as our planet existed for more than 4 billion years before humans appeared, it will last for another 4 billion to 5 billion years, long after it becomes uninhabitable for humans.
You will age slowest on Mercury, Venus and Jupiter as they are slower than Earth. You will age a couple of minutes faster on Mars as it is less massive and has less gravity than Earth.
Use the table below and a calculator to determine your age on a particular planet. If you are exactly 12 years old, that's 4 380 days (12 x 365). It would also mean that today is your birthday. If, however, you lived on Mercury and had a birthday every 88 days then you would be nearly 50 years old (4 380 ÷ 88 = 49.77).
Not much is known about Pluto, the only planet that has not been visited by an explorer spacecraft, and our best image of its surface is a hazy picture taken by the Hubble Space Telescope in 1996. The mission will also study the surrounding Kuiper Belt, which is made up of thousands of icy, rocky objects.
