Do you know that if you drive the minimum distance to Mars at an average highway speed of 100 kmph (62 miles per hour) - it would still take more than 66 years to reach this Red Planet called MARS.
A spacecraft takes about six months to get to Mars.
But it takes sunlight about four minutes longer to get to Mars than to get to Earth.
Do you know that Jupiter is one of the most non human-friendly planets to visit?
The radiation level encountered by spacecraft visiting Jupiter is more than 1,000 times the lethal level for a human being. Even heavily-shielded spacecraft like Galileo were damaged by its radiation level.
Do you know that though Uranus and Neptune are much smaller than our solar system's two other giant gas planets, but you could still pack nearly 60 Earths inside each of these planets?
The strangest fact is that some storms in Neptune's clouds are as big as Earth.
Do you know Neptune is a big ball of gas that gradually becomes hot liquid well below the clouds? There's nothing to land on. Anyone who would try to drop below the cloud tops would be torn by intense winds, frozen by super cold temperatures and eventually smashed by the sheer weight of the atmosphere above, which, by the way, is harmful for humans.
It's hard to imagine, but Saturn is the only planet in our solar system that is less dense than water. The giant gas planet could float in a bathtub - if such a colossal thing existed.
Do you know that Earth's atmosphere does more than just giving us air to breath? It shields us from protects us from most meteorite impacts and almost all the harmful radiation of the Sun. Without our atmosphere, Earth would have been a lifeless, cratered hunk of rock such as the Moon or Mercury.
Our Solar System
Do you know that to detect those tiny signals from space, the Deep Space Network uses antennas with diameters of up to 70 meters (230 ft).
