Tags Earth Orbit Sun The sun Time In summary, the time it takes for Earth to orbit the sun is not exactly 365.25 days, but it is close enough for us to have leap year every 4 years. It is coincidental, which becomes obvious once you realize that the year is not only not 365.25 day...

Time to clean up low Earth orbitAlthough space debris has been a problem for decades, recent investment in active debris clearing shows a wider commitment to sustainable space development.doi:10.1038/s41550-022-01816-7Nature Publishing Group UKNature Astronomy...
The Enterprise crew catch a virus that removes their inhibitions. The USS Enterprise orbits the planet Psi 2000, a world that was much like Earth in its distant past, tasked to observe the planet's impending disintegration. Lieutenant Commander Spock and
It is estimated that more than 22,300 human-made objects are in orbit around the Earth, with a total mass above 8,400,000 kg. Around 89% of these objects are non-operational and without control, which makes them to be considered orbital debris. These numbers consider only objects with di...

A Falcon 9 rocket lofted 23 Starlink craft to low Earth orbit today, lifting off from Florida's Cape Canaveral Space Force Station at 6:22 p.m. EST (2322 GMT). The rocket's first stage made its descent back to Earth eight minutes after liftoff, landing on the droneship Just...
The module did not have any astronauts inside and was “lost” although it was released in such a way that it would go into orbit around the Sun. The module was located in 2019 using a telescope. As for other types of accidents, there have been, cases of satellites that have collided ...
