Ceres (/ˈsɪəriːz/; minor-planet designation: 1 Ceres) is the largest object in the main asteroid belt between the orbits of Mars and Jupiter….Ceres (dwarf planet)

Ceres has an extremely small and thin atmosphere because it cannot retain gas particles with its weak gravity, meaning that its atmosphere is primarily composed of water vapor that escapes whenever solar radiation hits its surface ice.

According to NASA, Ceres is about 413 million kilometers from the Sun and inhabits the asteroid belt region between Mars and Jupiter. Thankfully, this gigantic asteroid is very far from Earth and is not in danger of colliding with the planet.

A ‘Megasatellite’ Orbiting Ceres Would Make a Fine Home For Humans, Scientist Says. Given all the logistics involved, it’s unlikely that humanity will ever see our way outside the Solar System to colonise exoplanets. But the possibility of settling elsewhere inside the Solar System isn’t so far-fetched.

Humans could be living in a ‘floating asteroid belt colony’ in 15 years’ time, scientist says. In a research paper published this month, Dr Janhunen says humans could be living on floating orbs in the asteroid belt located between Mars and Jupiter within the next 15 years.

That means that according to the definition of the International Astronomical Union, the Earth cannot technically be considered as a planet and that it is, in fact, a dwarf-planet. There were seven earth sized objects discovered in orbit around an ultracool dwarf star forty light years away using this method.

Based on his Copernican principle, J. Richard Gott has estimated that the human race could survive for another 7.8 million years, but it is not likely to ever colonize other planets.

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

In this scenario, a wormhole would be an extremely curved region in spacetime that resembles two interconnected funnels and connects two distant points in space, like a tunnel. “From a mathematical perspective such a shortcut would be possible, but no one has ever observed a real wormhole,” the physicist explains.

There are many instances of animal and human bodies found in the ice, frozen, yet preserved and not damaged by the extreme temperature. This makes the concept of a ‘cryosleep’ sound doable. The first person to be cryopreserved was Dr. James Bedford in 1967.

Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.

Using NASA’s Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light. When matter gets close enough to a black hole, it enters into a swirling pattern called an accretion disk.

Fastest human-made object: 244,255 mph (393,044 km/h).

How fast can conventional rockets go?

Surprisingly, the fastest manned mission record still belongs to Apollo 10, which took place back in May 1969. During its return from the Moon, the crew’s vehicle reached a speed of 24,791 mph (39,897 km/h).

Voyager 2’s current relative velocity to the Sun is 15.436 km/s (55,570 km/h; 34,530 mph).

Typical examples

Understanding g-force 100kph is 28m/s, 28 / 2.3 = 12m/s2, 12 / 9.8 = 1.2g.
