The radius of the visible Universe is estimated at 1.7e26 m (18 thousand million lightyears) plus or minus 20 percent or so.
The mass of Earth is 5.97 x 10 24 kg. Here that is written out: 5,970,000,000,000,000,000,000,000 kg. Yeah, thatâs a really big number. And yet, itâs only 0.3% the mass of Jupiter (and Jupiter is mostly lightweight hydrogen). We have written many articles about Earth for Universe Today.lue marble Earth. Image credit: NASA. First, the equatorial diameter of Earth is 12,756 km. In other words, if you dug a tunnel on the equator that went straight down and went right through the center of the Earth, it would be about 12,756 km long.
