Updated September 30, 2024 at 1:22 PM. Earth has a new “mini- moon ” after an asteroid has joined our orbit. The object, known as 2024 PT5, has been chasing after us for years. Now, it has ...
The Lunar Gateway, or simply Gateway, is a space station which is planned to be assembled in orbit around the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts as part of the Artemis program. It is a multinational collaborative project: participants include NASA, the European ...
In order to be considered a mini-moon, an incoming body must reach Earth at a range around 2.8 million miles (4.5 million km) and at a steady space of about 2,200 mph (3,540 km/h), according to ...
During its 56-day orbit, Asteroid 2024 PT5 will travel in a horseshoe-shaped trajectory before leaving Earth's gravity. 2024 PT5 will make a horseshoe-type orbit around the Earth. The study dubbed ...
For the orbit of the Moon around the Earth, see Orbit of the Moon. Orion capsule of Artemis 1 above the Moon in December 2022. In astronomy and spaceflight, a lunar orbit (also known as a selenocentric orbit) is an orbit by an object around Earth's Moon. In general these orbits are not circular.

Every 18.6 years, the angle between the Moon's orbit and Earth's equator reaches a maximum of 28°36′, the sum of Earth's equatorial tilt (23°27′) and the Moon's orbital inclination (5°09′) to the ecliptic. This is called major lunar standstill. Around this time, the Moon's declination will vary from −28°36′ to +28°36′.
Earth orbit (yellow) compared to a circle (gray) Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), or 8.317 light-minutes, [1] in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million ...
