Not exact matches

Oh, so in the vast known Universe, which reaches out for 15 BILLION light years in all directions, with over 100 BILLION galaxies, containing an average of 100 BILLION stars each, with most of those stars now thought to have multiple planets orbiting around them, you can't imagine that there would be at least ONE little planet SOMEWHERE with the right conditions for life without divine intervention?

The International Astronomical Union defines «planet» as a celestial body that, within the Solar System that is in orbit around the Sun; has sufficient mass for its self - gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape; and has cleared the neighbourhood around its orbit; or within another system, it is in orbit around a star or stellar remnants; has a mass below the limiting mass for thermonuclear fusion of deuterium; and is above the minimum mass / size requirement for planetary status in the Solar System.

We would expect this disc to settle around the star's middle, so planets in our solar system ought to orbit in line with the sun's equator.

They suggested that the magnetar formed through the interactions of two very massive stars orbiting one another in a binary system so compact that it would fit within the orbit of the Earth around the Sun.

Synchronous orbits exist around all moons, planets, stars and black holes — unless they rotate so slowly that the orbit would be outside their Hill sphere.

The theory goes that before exploding, the progenitor star has its hydrogen outer coat stolen by a companion star in orbit around it, but astronomers have never before been able to spot the thieving companion because the supernova is so bright.

The planets» rotation is locked, so the worlds keep the same face towards the stars they orbit, much like the Moon does as it moves around the Earth.

For example, as Kepler has spotted 1,235 exoplanet candidates so far - 53 of which orbit stars in their habitable zones - knowing approximately how many stars there are in our galaxy (there are thought to be around 300 billion stars in the Milky Way), an estimate can be made of how many worlds are orbiting these stars.

Around smaller, less massive and dimmer dwarf stars, however, planets would have to orbit closer in order to sustain a surface temperature that is warm enough to keep water liquid and so the star would appear larger in the sky.

So - called circumbinary planets — those planets that orbit around a binary star, like the fictional Tatooine from the Star Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org prepristar, like the fictional Tatooine from the Star Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org prepriStar Wars — can be ejected off into space as a consequence of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org preprint).

Moreover, the brown dwarf companion to 15 Sge may eventually prove to have a highly circular orbit that is coplanar with the circumstellar disk so that planets formed in inner orbits around the star.

The TRAPPIST - 1 exoplanets are packed in a tight orbit around their dim parent star and are so close to one another that all of their orbits would fit inside Mercury's orbit of the sun.

With a torch orbit around its host star that takes only about 20 hours (84 percent of an Earth day) to complete, Kepler 10b has an average orbital distance of only 0.017 AU from its host star and so has a tidally locked, synchronous orbit.

With a semi-major axis of 0.066 AUs, it orbits so close to its host star that its orbital period lasts only 8.78 days, and so the planet must be very hot at around 450 ° Kelvin, 351 ° F, or 177 ° C (Forveille et al 2008).
