Sentences with phrase «n't orbit around a star»

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?

Captured by Kepler's digital sensors, transformed into bytes of data, and downloaded to computers at NASA's Ames Research Center near San Francisco, the processed starlight slowly revealed a remarkable story: A planet not much bigger than Earth was whipping around its native star at a blistering pace, completing an orbit — its version of a «year» — in just over 20 hours.

Not necessarily, says Harvard astrophysicist Matt Holman, who has used a computer to simulate how a planet around a binary star would behave over millions of orbits.

The first planets outside the solar system were discovered 25 years ago — not around a normal star like our Sun, but instead orbiting a tiny, super-dense «neutron star».

In fact, last week, astronomers found a rocky planet not much bigger than Earth whose orbit around its relatively young star is only 3 % of the distance from Earth to the sun (ScienceNOW, 21 April).

Roughly a fifth of the observed stars weren't following the standard orbit around the Milky Way, the researchers report in the October issue of Astronomy & Astrophysics.

The star around which Kepler 78b orbits is likely relatively young, as it rotates more than twice as fast as the sun — a sign that the star has not had as much time to slow down.

We realized that with the most common kind of star in the sky, the red dwarfs, you wouldn't know if it were orbiting around our sun.

He pointed out that there are many close - orbiting planets around middle - aged stars that are in stable orbits, but his team doesn't know how quickly this young planet is going to lose its mass and «whether it will lose too much to survive.»

In addition, these stars are not orbiting the galactic center inside the Milky Way's spiral arms like the Sun, but they originate from the spherical Galactic halo that surrounds the Milky Way's main disk, while briefly intersecting it in their long, elliptical orbits around the center.

Found via radial velocity variations, the planet's true mass could not be known with knowing whether its orbit around Star B is being viewed edge - on, face - on, or somewhere in between.

On March 25, 2015, a team of astronomers using the Hubble Space Telescope revealed observations which indicate via the transit method that Alpha Centauri B may have a second planet «c» in a hot inner orbit, just outside planet candidate «b.» After observing Alpha Centauri B in 2013 and 2014 for a total of 40 hours, the team failed to detect any transits involving planet b (previously detected using the radial velocity variations method and recently determined not to be observed edge - on in a transit orbit around Star B).

KELT - 9b has an extremely short orbital period, a near - polar orbit and travels around a star that is oblate, not spherical, co-author Karen Collins, a post-doctoral fellow at Vanderbilt, noted.

Assuming that the spectroscopic companion B does not preclude a stable inner planetary orbit, the distance from Star A where an Earth - type planet would be «comfortable» with liquid water is centered around only 0.457 AU — between the orbital distances of Mercury and Venus in the Solar System.

«Tau Ceti has been a popular destination for science fiction writers and everyone's imagination as somewhere there could possibly be life, but even though life around Tau Ceti may be unlikely, it should not be seen as a letdown, but should invigorate our minds to consider what exotic planets likely orbit the star, and the new and unusual planets that may exist in this vast universe,» says Pagano.

The analyses did not resolve whether the perturbing body orbits Sirius A or B, although dynamical simulations suggest that stable orbits exist around both stars at circumstellar distances up to more than half the binary system's closest separation of 8.1 AUs (Daniel Benest, 1989).

However, if the existence of a relatively close, second companion (see Star Bc below) around Bab — with an orbital period of 2.2 to 2.9 years or less — is confirmed, then a planetary orbit in Star Ba's water zone may not be stable over the long run.

The detection of close - in giant planets around other stars was the first clue that this pattern is not universal, and that planets» orbits can change substantially after their formation.

Model fits for the orbits of T Tau Sa and Sb around each other and around T Tau N yield orbital elements and individual masses of the stars Sa and Sb.

Finally, noncoplanarity between the component stars of a binary system should not have a significant impact on the stability of close - in planetary orbits around each star (Alan Hale, 1994).

Indeed, stable orbits may extend as far as one third of the closest separation between any two stars in a binary system, but according to NASA's Kepler Mission team, numerical integration models have shown that there is a range of orbital radii between about 1/3 and 3.5 times the stellar separation for which stable orbits around two stars are not possible (Holman and Wiegert, 1999; Wiegert and Holman, 1997; and Donnison and Mikulskis, 1992).
