How high must a satellite orbit to stay perfectly synchronized with Earth’s rotation? 🌍 This video determines the exact orbital altitude required for a geosynchronous orbit, clearly explaining the ...

That misalignment means the tidal bulges pull on the Moon gravitationally, which gradually speeds up the Moon’s orbit. When ...

When my colleagues and I send them out to explore our solar system, it's important for us to understand the 3D map of our ...

In the bigger picture, "down" could be defined as being below the plane of the solar system, which is known as the ecliptic.

Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Study finds Mars helps pace Earth's ice ages through gravity. Remove Mars, and a major 2.4-million-year climate rhythm ...

Earth’s slow axial wobbles—known as precession cycles—do not just shape long-term climate trends. A new study led by ...

At the start of the year, Earth will quietly reach a milestone in its orbit around the sun. Known as perihelion, this is the moment when our planet is closer to the sun than at any other point in the ...

Despite the winter solstice being the shortest day, the sun has been rising later in the weeks following it. This phenomenon is due to the Earth's elliptical orbit and axial tilt, which causes a ...

SpaceX may have launched 10,000 Starlink satellites into orbit, but now it's got big competition. As in literally, physically big. Texas-based AST SpaceMobile has just launched the largest satellite ...

Billions of years ago, a day on Earth did not last 24 hours. New research suggests that for about one billion years, each day stayed fixed at roughly 19 hours because of a balance between the oceans, ...

SpaceX recently confirmed that one of its Starlink satellites orbiting the planet has exploded, effectively rendering the spacecraft useless and is currently tumbling down for its re-entry. Over the ...
