There's a new interstellar comet in the neighborhood! Known as 3I/ATLAS, this comet poses no threat to Earth – but it does ...

At the aphelion, the distance from the Earth’s center to the Sun’s center is going to be 152,087,738 kilometers (94,502,939 ...

Astronomers have detected an object with an orbit that will take it out of the Solar System, and almost certainly must have ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

New research on the orbits of these mysterious asteroids near Venus stress the need for better space rock surveillance.

Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather ...

Many people experience diarrhea while on their period (commonly known as “period poops”). We spoke to doctors about what causes the phenomenon and how best to manage stomach-related issues ...

On December 30, ISRO's workhorse, the Polar Satellite Launch Vehicle (PSLV), lifted off with twin 220-kg satellites for space and released in a 470-km circular orbit.

Earth's orbit periodically varies from more circular to a lot more elliptical because of the gravitational effects caused by the Moon and other space bodies over large periods of time.

Two medium Earth orbits are notable: the semi-synchronous orbit and the Molniya orbit. The semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the ...

Intelsat 33e launched in August 2016 to geostationary orbit (GEO), a circular orbit above Earth’s equator that has the same orbital period as Earth’s rotation, and began operations in January ...

Once in a lower and more circular orbit, the space plane will then jettison its service module components. This means the components will remain in orbit for a much shorter period of time than if ...
