This may explain the strange properties of the orbits of our solar system's planets, which are not quite perfectly circular, and all lie on slightly different planes. NASA artist’s conception of ...

A 1-in-83 chance of an impact represented a 1.2% chance of an impact. That meant there was a 98.8% that 2024 YR4 would miss ...

The orbits of the planets around the sun have been ... suggesting it is unlikely the current theories can explain observations. Instead, they demonstrate that an object with between two to 50 ...

Earth orbits are generally described in terms of altitude and are categorised into different sections. In high orbits, 22,000 miles (36,000km) above Earth, satellites enter a geostationary ...

This means that objects in small orbits travel faster than objects in large orbits. The graph shows how the orbital speed of a planet changes with its distance from the Sun. Polar orbits take the ...

The three astrophysicists found that a distinctive, close flyby of another star can explain the inclined and eccentric orbits of the known trans-Neptunian celestial bodies. "Even the orbits of ...

Previous theories suggested that the orbits may have been reshaped due to ... this belief and argues that a one-off event could explain these irregularities. The scientists added that further ...

NASA and European scientists explain how they calculate the probability of the space rock 2024 YR4 impacting our planet, and why it’s not yet time to worry.

the existence of a cluster of large population of TNOs with orbits beyond Neptune’s gravitational influence—can be explained by the presence of an Earth-sized planet, according to the paper.
