Viewed from above, our solar system's planetary orbits around the sun resemble rings around a bulls-eye. Each planet, including Earth, keeps to a roughly circular path, always maintaining the same ...

(Nanowerk News) Viewed from above, our solar system’s planetary orbits around the sun resemble rings around a bulls-eye. Each planet, including Earth, keeps to a roughly circular path, always ...

The eight planets in our solar system (yes, it's still weird for me to write "eight," too) orbit the sun in roughly circular paths, although they're ever-so-slightly ellipses instead of circles. A new ...

Researchers based at Aarhus University measured the orbital eccentricity of 74 small extrasolar planets and found their orbits to be close to circular, similar to the planets in the solar system, but ...

The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...

An international team of astronomers has discovered eight new extrasolar planets, bringing to nearly 80 the number of planets found orbiting nearby stars. The latest discoveries, supported by the ...

How does a planet’s size influence its orbit around its parent star? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of ...

Of all the planets in the solar system, Earth is distinctly hospitable to life because of its distance from the sun. As our planet follows its orbit, it gets sufficiently close to the sun as to take ...

A team of researchersfrom MIT and Aarhus University, Denmark, have discovered thatEarth-sized exoplanets orbit their parent stars in the same way thatour planet orbits our own Sun – maintaining a ...

The irregular shapes and orbits of Mars’s two small moons, Phobos and Deimos, have long been a subject of scientific curiosity. Recent research suggests that these moons may have originated from ...
