Why does a ball land on Jupiter faster than it does on Earth and Uranus?  News

Jaxa scientist created an animation about how fast an object can fall on different stars.

James O’Donoghue, a scientist at the Japan Aerospace Exploration Agency (JAXA), created an animation about how fast an object can fall to the surface of the Sun, Earth, the dwarf planet Ceres, Jupiter, the Moon, Pluto, and other stars. .

This animation shows how a sphere falls to the surface of a turbulent star from a height of a thousand meters at a speed that is thought to be airborne.

“It should give you an idea of ​​how to pull each object … It would be amazing if the big planets had a comparable attraction to the smaller ones,” Odonog says.

For example, explain that Uranus pushes the ball down more slowly than it does on Earth. This is due to the low density of Uranus moving the surface away from most of the mass. DW

“Similarly, Mars has twice the mass of Mercury, but you can see that the gravity of the surface is really the same, (…) which indicates that Mercury is denser than Mars,” he explains.

Located in the asteroid belt between the orbits of Mars and Jupiter, Ceres is the slowest spacecraft to fall, falling 1 km in 84.3 seconds.

When in the sun, it takes 2.7 seconds for the ball to fall; When on Earth, 14.3 seconds. (I)
