Uranus just got a little more time on its hands ... for calculating coordinates on the enigmatic world and mapping its surface. Scientists may need to rethink some of those maps, a new study ...

However, at Neptune’s surface, the gravity is only about 1.1 times the gravity we experience on Earth. In other words, if something weighed 100 pounds on Earth, you would find it weighs 110 pounds on ...

Gravity on the surface, g in N/kg 11.2 Use a set of bathroom scales to measure your mass in kg. Then use the table above and the equation: Weight = mass x gravity to investigate how your mass and ...

Its surface gravity is 37.5 percent of Earth’s. Mars rotates on its axis every 24.6 Earth hours, defining the length of a Martian day, which is called a sol (short for “solar day”).

Like other gas-giant planets, Uranus doesn’t have a rocky surface to look at. So scientists must deduce its rotation period by tracking its internal magnetic field over time. Laurent Lamy at the ...

NASA wants to come up with a way to transform 96 sacks of feces, urine and vomit ditched by Apollo 11 astronauts in1969.
