While NASA warns of five more space rocks on their way to Earth, one Finnish astrophysicist proposes human colonization of the asteroid belt within the next 15 years.
As Earth orbits in the month one of 2021, NASA has ordered that five more asteroids, potentially between 25 and 100 meters (82 and 98 feet) in diameter, should be near flight levels before the month is over. is.
On Tuesday, the 25-meter asteroid 2021 BD3, with a diameter of about half the height of the Arc de Triomphe, will pass the planet at a safe distance of 3.9 million km (3.9 million miles). A short time later, an object called 2021 AL, which has a diameter of 40 m or measures about five London buses end-to-end, will float past at a distance of 4.1 million km.

The next, on Thursday 28 January, is the 40-meter space rock 2021 BZ that shoots past at 2.1 million km.
To round off a rocky start to the year on 29 January, asteroids 2021 will hit AG7, which can be up to 100m in diameter or the same size as the Big Ben in London, and the 30m 2021 AF7 the Earth at 4.2 million km. and 6.8 million km, respectively.
Meanwhile, one forward-thinking astrophysicist suggests that humans, rather than asteroids coming to us, should rather colonize the asteroid belt, in as little as 15 years.
Dr Pekka Janhunen, an astrophysicist at the Finnish Meteorological Institute in Helsinki, suggested building habitable floating “megasatellites” around the dwarf planet Ceres, about 523 million kilometers from Earth, between the asteroid belt between Mars and Jupiter.

Like something taken straight from modern science fiction series, these disc-shaped settlements, coupled with powerful magnets, boast thousands of cylindrical structures that could accommodate a total of 50,000 people, all benefiting from artificial gravity generated by slow-moving floating cities. .
Janhunen also proposes space exploration of Ceres as a way to set up an economy and make colonization profitable and sustainable, using space elevators to carry resources back to the pods and possibly back to earth for processing .
