The Moon Distance Calculator shows approximate times for when the Moon is closest to the Earth (perigee) and furthest from the Earth (apogee).
The spacecraft sits in a low-Earth orbit, around 300 miles from the planet’s surface, and that means it is affected by the planet’s atmosphere. “The sun is constantly spewing out charged particles and radiation at multiple wavelengths. What happens when it hits the Earth’s atmosphere is...
The reason why we cannot see the entire illuminated hemisphere of the Moon during some Full Moons is that the Moon’s orbit around Earth is inclined at an angle of about 5° in relation to the Earth’s orbital plane, theecliptic. If the Full Moon occurs at a moment when the Moon is ...

the Yearly Horoscope is a celestial roadmap, deciphering the language of the stars to illuminate the path ahead. It’s an invitation to explore the profound interplay between the cosmic and the personal, offering a nuanced understanding of how celestial dynamics may set the tone for the unfolding...
Before getting to the Moon, SpaceX and Blue Origin must master the technologies and techniques required for in-space refueling. Right now, SpaceX is scheduled to attempt the first demonstration of a large-scale propellant transfer between two Starships in orbit next year. ...
Here’s how it works. This year skywatchers will get to witness three supermoons in a row on Jan. 21, Feb. 19 and March 20. A supermoon occurs when a full moon coincides with the moon's perigee, or the point in its elliptical orbit at which it is closest to Earth. This makes ...
surface. The Moon has low gravity and no atmosphere, so the dust is thrown up in a huge plume. The dust cloud could possibly interfere with the navigation and science instruments or cause visual obstructions. Additionally, the dust could even be propelled into orbit, risking other spacecraft ...
