How many satellites are there, and which are there on each planet?

If you count all the little nuts, bolts, loose wrenches and pieces of demolished satellites as satellites, then there’s a whole lot of junk floating around Earth. Thousands of pieces that pose a hazard. Around the moon we have about three functioning spacecraft but have launched far more than that that have, over time, gone... Continue Reading →

Perhaps human race’s home was not Earth in the first place, but in another planet, and we came here to prevent extinction

Mechanical, intentional interstellar travel is unlikely since the distances are far too great to imagine. The best anyone could achieve is interplanetary travel within one’s own solar system. Therefore, if we pass the buck and say life didn’t start here but started somewhere else and arrived here, it would have had to arrive on a... Continue Reading →

Why are we so obsessed with finding the smallest amount of life on another planet when we have amazing life that we take for granted here on Earth and we destroy it?

We have no proof life exists anywhere in the universe other than Earth. Given a planet with the right conditions, life can spring from matter and eventually evolve into something greater is the wet dream of science, but still an unproven theory.

How long would it take to travel to the nearest star?

Proxima Centauri, is our nearest star, about 4 light years away. A light year is the distance light travels in one year, or 9,460,730,472,581 kilometers. That's 9.46 trillion kilometers, or about 5.88 trillion miles. The fastest space ship we ever built was the Juno spacecraft, which in 2016 broke all speed records in space with a...

The four gas giants are larger than Earth: Jupiter, Saturn, Uranus and Neptune. Venus is slightly smaller, but very nearly the same size as Earth. Mercury and Mars are smaller than Earth. So there are 4 planets larger than Earth in our solar system, and they are the four gas giants.
