NASA is preparing astronauts for their return to the Moon - and they’ve brought a piece of the Moon to Earth to do it. Using ...

Early predictions suggested a 1% chance of a collision with Earth, a figure that was later revised to a remarkably low 0.004% ...

YR4 won’t hit Earth, but a 4% chance remains for a lunar impact. ESA's upcoming NEOMIR telescope could revolutionize early ...

A COLOSSAL asteroid on a collision course with the Moon could damage thousands of satellites and send shrapnel blasting ...

But in space or on the Moon, there are no power lines, no sunlight at night and no backup grid. Every system — from life ...

The whole problem is that, on the scale of the solar system, the Earth and moon are so close together that you can't see their relative motion. But I'm sure textbook authors will keep trying.

Earth doesn't really have a second moon—but here's what would happen if we did. If you were hoping to see the “mini moon,” you’ve probably been disappointed.

The short answer is that you would weigh roughly one-sixth your Earth weight on the Moon. So if your bathroom scale reads 180 pounds (81.6 kilograms) on Earth, it would read 30 pounds (13.6 kg) on ...

The asteroid, measuring between 130 to 300 feet wide, was discovered in December 2024. While the risk to Earth is negligible, 2024 YR4 has a slightly higher chance of impacting the moon.

The Moon’s albedo is 0.136, while the Earth’s is 0.434, making the Earth 3.2 times as reflective. That figure varies of course, depending on cloud and whether you’re facing mostly ocean or land.

Scale and grandeur The red planet is currently about 250 times more distant than the Moon. As of Tuesday, Mars is roughly 60 million miles (96 million kilometers) away.

China has successfully established the world's first three-satellite constellation on the distant retrograde orbit (DRO) in the Earth-moon region of space, connecting them with stable inter ...
