The ATLAS (short for Asteroid Terrestrial-impact Last Alert System) is a NASA-funded program developed by the University of ...

As mentioned above, most objects we send into space are headed for low Earth orbit. This is where you'll find the International Space Station (210 miles), the Hubble Space Telescope (370 miles), and ...

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

Earth’s orbit around the Sun is not circular, but an ellipse that is slightly elongated with an eccentricity of 0.017. (An eccentricity of 0 is a circle, while the dwarf planet Pluto has a ...

How much the Earth’s orbit deviates from a perfect circle is measured by its eccentricity. The higher the eccentricity, the more elliptical the orbit. Terry Virts/Johnson Space Center, via NASA ...

Researchers from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences and Columbia University ...

Some orbits are ever so slightly elliptical (like a somewhat squashed circle, or, in astronomical terms, an orbit with low eccentricity), whilst some appear rather flattened (highly eccentric orbits).

The moon will soon have a companion in Earth's orbit for a limited time. An Arjuna asteroid will become a "mini-moon" event for nearly two months starting Sept. 29, according to a study published ...

Pluto, for example, has a highly elongated orbit compared to the planets in our solar system and has an orbital eccentricity of 0.25. Earth has an orbital eccentricity of just 0.02.

A new interstellar object, A11pl3Z, has been discovered in our solar system, marking the third such object to be observed. It ...

For comparison, Earth 's orbit has an eccentricity of 0.0167 and is therefore close to circular; at the other extreme, an orbital eccentricity of 1 would be parabolic.
