In terms of size relative to its parent planet, the Moon is unusually large. Its diameter is 3476 kilometers (2160 miles), which means it is around 27 percent the size of Earth. The next biggest moon in the solar system by this measure, Triton, is only about 5 percent the size of i...
The Chicxulub impactor was an asteroid or comet at least 10 kilometers (6 miles) in diameter. Around 66 million years ago, it impacted a few miles from the present-day town of Chicxulub in Mexico, at around 64,000 kilometers per hour (40,000 mph). The impact has created a crater ...
On average, Jupiter is located 497 million miles (800 million kilometers) from Earth, so reaching it without an enormously powerful rocket or thousands of pounds of onboard propellant requires some careful strategizing by mission planners. And the plan for Juice’s journey was in the works for...
(or about 271 meters) in diameter, making it comparable to the length of three football fields laid end to end. Its nearest distance to Earth during this approach is some 1,770,000 miles away, equivalent to around 2,850,000 kilometers. Despite the vastness of these numbers, in t...
62. The distance a spaceship can travel in an hour depends on its speed. For example, the Apollo spacecraft could travel about 37,000 kilometers (23,000 miles) in one hour. 63. You can jump higher on the Moon than on Earth because the Moon's gravity is about 1/6th of Earth's ...
having a sidereal period of revolution about the sun of 365.26 days at a mean distance of approximately 149.6 million kilometers (92.96 million miles), a sidereal rotation period of 23 hours 56.07 minutes, an average radius of 6,378.1 kilometers (3,963 miles), and a mass of approximately ...
It has a diameter of 7,926 miles (12,756 kilometers) at the equator, and it has a mass of about 6×1024 kilograms. The Earth orbits the Sun at a speed of about 66,638 miles per hour (29.79 kilometers per second). Don’t dwell on those numbers too long, though; to a lot of...
“In order to become a mini-moon, an incoming body has to approach Earth slowly at close range,” de la Fuente Marcos said. Asteroids that become mini-moons come within 2.8 million miles (4.5 million kilometers) of Earth at speeds under 2,237 miles per hour (3,600 kilometers per hour...
