The simulation reveals that the asteroid’s path, marked as a red line, traces a partial orbit around Earth, spanning approximately 25% of the planet. Interestingly, 2024 PT5 won’t complete a ...

Getting to the moon takes a lot of small steps, like Europe's new LUNA training facility. But it's not there yet. Next step: ...

Current theories of the Moon’s formation favor both the Earth and Moon forming from the debris created by the collision of a Mars-sized world with the proto-Earth about 4.5 billion years ago.

That’s why spacecraft often leave Earth only to arrive back at our planet a few months or years later, performing a flyby maneuver. In Juice’s case, it launched in 2023, and has now swing back ...

An newly discovered asteroid will be captured by Earth's gravity this fall. The "mini-moon" will spend about two months in Earth's orbit, before being flung back on its normal path around the sun.

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

The moon's diameter of about 2,160 miles (3,475 km) is a bit more than a quarter of Earth's diameter. The lunar mantle is the layer located beneath the crust and above the core, spanning a depth ...

Earth is about to gain a new “mini-moon,” but it won’t stay around for long. The newly discovered asteroid, named 2024 PT5, will temporarily be captured by Earth’s gravity and orbit our ...

The newly discovered asteroid, named 2024 PT5, will temporarily be captured by Earth’s gravity and orbit our world from Sept. 29 to Nov. 25, according to astronomers.

The moon’s gravity slightly bent Juice’s path so it received a much larger gravity assist from Earth. The flyby of Earth reduced Juice’s speed by 10,737 miles per hour (4.8 kilometers per ...
