Earth is 93 million miles (150 million km) from the sun. 40,000: The approximate number of years it would take an unmanned spacecraft like NASA's Voyager 1 probe now leaving our solar system to reach Alpha Centauri Bb. You'd need a lot of snacks for that trip. 2,240: The likely ...
Researchers say the black hole is just 1,000 light-years away from Earth — closer to our solar system than any other found to date. 1,000 light-years may seem far away, but on a cosmic scale, it's incredibly close. In comparison, Sagittarius A*, the infamous supermassive black hole ...
Obviously, the top titleholder on this list is the central star of oursolar system: the Sun. Yes, it's a star and a very nice one at that. Astronomers call it a yellow dwarf star, and it has been around for about five billion years. It illuminates the Earth in the daytime and is...
Proxima Centauri is the closest star to this solar system. A couple of years ago, a team discovered that there is a planet – called Proxima b – orbiting the star. It’s just a little bit bigger than Earth, it’s probably rocky and it is in what is called the...
