Planets change orbit shape around Neptune’s size. Metal-rich stars help giant planets form. Eccentric orbits suggest chaotic planet formation.

Scientists have detected a potential exoplanet using an unusual method — tracking shifts in another planet’s orbit. The hot Jupiter TOI-2818b was found to have an unexpected timing variation, hinting ...

Faint signatures detected by the Canada France Hawaii Telescope have revealed 128 new moons around Saturn, making it the indisputable frontrunner for having the most moons in our solar system.

Greenhouse gas emissions could reduce drag in the upper atmosphere, leaving more space debris in orbit and making satellites ...

The planets orbit the sun continuously in the solar system, so at times, they slowly catch up to one another. Because they travel along the same path, or ecliptic, as they pass Earth, it appears they ...

A new study from MIT aerospace engineers reveals that rising carbon dioxide levels are shrinking Earth’s upper atmosphere, ...

That path is called the ecliptic, and it exists because all planets in our solar system orbit around the sun on roughly the same plane. Astronomers, on the other hand, look for more specific ...

YR4 has a very small chance of striking Earth when its orbit briefly intersects our planet's in December 2032.
