Possiblity of Life on your Body.
Io has liquid lava. Io has its own magnetic field. There is no oxygen on Io. There can't life on Io unless it's filled with Fire Aliens or Dragons, which i doubt it'll exist.
Mars is located next to Earth. It has been shown there has been oxygen. On Earth, wherever there's water, scientists find life; deep underground, under rocks in Antarctica, or inside nuclear reactor tanks. Life always finds a way. And so, the search for life on Mars will involve the search for water.
I think Mars has the highest possibility of life being on it.
Extra : Earth : The moon does not have any liquid water because of the extreme temperatures. Any liquid water exposed to sunlight on the moon evaporates instantly and escapes into space. Any water left in the shadows of craters are turned into ice. This leaves us with no liquid water left.

Earth to Io.
Km, au , and light years. are almost the same. 1 au equals to 150,000,000 kilometers (km). Light years measure more further, like earth tom galaxy or the nearest star ( not the sun). Kilometers are mainly use between planets, Au is just a better simplify.
NASA's Galileo spacecraft was originally supposed to take only 2 years to reach Jupiter following a direct flight path. It was supposed to launch from the space shuttle Challenger, but after the disaster, NASA decided to give it a slower route that involved several gravitational flybys around Venus and Earth. In the end, it took about 6 years to reach Jupiter. NASA's New Horizons spacecraft, the fastest spacecraft ever launched, took just 13 months to reach Jupiter from Earth.
I do not think humans are able to land on io. Io is full with volcanoes. It is extremely hot and dangerous, one land can kill a person quickly, or might even get melted.
The minimum distance between Jupiter and Earth is 588 million km (365 million miles). Since one light year (the distance light travels in one year) is approximately 5,870,000,000,000 miles, the minimum distance between Jupiter and Earth is 0.0000621 light years.

More Information and Facts about Io.
Size: 3,632 km (2,257miles) wide, slightly larger than Earth's moon.
Distance From Jupiter: 422,000 km (262,230mi)
Io is made of rock with a melted metal core
Io's hundreds of volcanoes spew 11 billion tons of lave per year! What causes these huge eruptions?
The gravity of nearby Jupiter and other moons tugs at Io. The strong pull cause Io to stretch and bend. This motion causes friction (rubbing) inside Io. When you rub your hands together quickly for 30 seconds. Friction causes heat! The heat melts most of Io's rock. The melted rock flows up and shoots out as lava. The heat also explodes underground gas that makes lava spray really high! ( Uses resources and organized).
Facts about Io.
At one-third the size of earth, Io is the most volcanically active body in the solar system. The nearest to Jupiter of the four large moons, Io's surface is full with volcanoes which erupt frequently, lava, dust and gases onto its landscape. Io is believed to have a metallic core. Its surface is mostly flat plains, but mountains as high as 9 kilometers have been observed by scientists on Earth.
Io's Deadly feature ( Extra )
Before the astronomers visited Jupiter, if you had described Io you'll probably think of volcanoes. Jupiter's strange moon is literally bursting with volcanoes. Dozens of active vents pepper the landscape with volcanic rings the size of California. The volcanoes themselves are the hottest spots in the solar system, with temperatures exceeding 1800 Kelvin (1527 Celsius) about 1/3 the temperature of the surface of the Sun! The flaming hot plumes which rise as much as 500 kilometers into space are so large they can be seen from Earth by the Hubble Space Telescope.
These high-rising, seem to be made up of, not hot lava, but frozen sulfur dioxide. For a world dominated by active volcanoes, it's curious that Io is also very, very cold. The ground just around the volcanic vents is literally sizzling, but most of Io's surface is 150 degrees or more below 0 Celsius which is astonishing.

Io accretion
First there is a Nebula of hot gas and dust from a super nova explosion. (Particles) As cloud cools, atoms move slower and clump together. Results of planetestimal accretion begins, small objects collide and stick together to form larger bodies. Protoplanet, big enough to pull more in, as it almost becomes a planet. Stays as a protoplanet because Jupiter pulls it to its orbit. Finally it was discovered by Galilieo's satellite and was named Io.

Planet?
Considering it meets most terms it is missing a important piece of governing objects in his neighborhood. It orbits the sun it is spherical. We now know that pluto is part of a Kuiper belt. It is past Neptune and is made of frozen gas and ice. My moon
, Io is not considered a planet. It orbits the planet Jupiter not a star.
