Earth’s orbit is getting crowded, and scientists are warning that space may soon become too risky to manage safely. A new ...

Orbital mechanics can be a bit counter-intuitive. We have to slow down an orbiting space craft to convert kinetic energy for gravitational energy. The orbital altitude is raised at its highest point ...

NASA confirms the discovery of Earth’s temporary second moon, 2025 PN7, a rare quasi-moon orbiting alongside Earth since the ...

Unlike the Moon, which is gravitationally bound to Earth, 2025 PN7 is classified as a quasi-moon — a near-Earth object that ...

Astronomers observe for the first time the actual motion of spirals in a protoplanetary disk, revealing gravitational ...

Astronomers identified asteroid 2025 PN7 as a quasi-moon of Earth in 2025, a rare celestial companion sharing Earth's solar ...

NASA has confirmed that Earth has a second moon, 2025 PN7, a small asteroid co-orbiting with our planet until 2083.

Orbital Mechanics is a fundamental discipline concerned with the motion of objects under the influence of gravitational forces, crucial for understanding both natural celestial phenomena and the ...
