Not exact matches

There's no scientific consensus as to how many of those stars might be like our own Sun, and how many may have Earth - like planets orbiting around them.

Spacecraft orbiting other planets won't be any help this time around for the same reason, but another set of instruments will step up: solar observatories like SOHO, STEREO and the Solar Dynamics Observatory, all of which are designed to stare straight at the sun's surface.

The process will demand at least three years to find a completely Earth - like planet: one that is in a yearlong, Earth - like orbit around a star just like the sun.

After a decade of searching for planets orbiting stars like our sun, astronomers had found nothing but giant planets, most of them gas balls like Jupiter, around other stars.

Like many of her colleagues, Spilker first began working on Cassini in the 1980s, some 30 years ago — about the same time as it takes Saturn to make one full orbit around the sun, and time enough to get family - close to colleagues, to raise children, to watch them grow.

Early in its mission, Kepler managed to find some tantalizing worlds, a handful of supersize cousins of Earth, most of them in clement orbits around smaller, cooler, quieter stars than the sun called M and K dwarfs, but all the setbacks made finding smaller Earth - sized planets around sun - like G stars a very tall order.

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».

It would be a different universe because, for example, bound orbits [like Earth's path around the sun] work only in three dimensions of space.

The pulse also knocked the electron into a highly elliptical path around the nucleus, rather like a comet that orbits the Sun but spends most of its time far outside the Solar System.

But, like Kepler - 186f, its 267 - day orbit also carries it around a star that is cooler and smaller than the sun, some 1,200 light - years away in the constellation Lyra.

They have really really long orbits around the sun, but like all orbiting bodies, they travel in predictable patterns.

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.

The failure, thus far, to find large substellar objects like brown dwarfs or a Jupiter - or Saturn - class planet in a «torch» orbit (closer han the Mercury to Sun distance) around 107 Piscium — with even the highly sensitive radial - velocity technique of Geoffrey W. Marcy and R. Paul Butler — bodes well for the possibility of Earth - type terrestrial planets around this star (Cumming et al, 1999).

Of the new planets, four are Earth - like planets, less than 2.5 times the size of our planet, and are within the habitable zone, the orbit area around a star where liquid water is possible, of their sun.

The Kepler spacecraft, which was launched in 2009 by NASA to find Earth - like planets orbiting other stars, has found yet another exoplanet, which orbits around a star much smaller and cooler than the sun.

A star's gravity keeps a planet moving in orbit, like Earth moves around our sun.

In 1996, astronomers announced the discovery of a Jupiter - like planet around this Sun - like star (Butler and Marcy, 1996 — details below), and there were indications of an even larger planet in an outer orbit.

Processes that have historically altered the face of the planet, like cycles in the Earth's orbit around the Sun or shifts in continental tectonic plates, occur over tens of thousands to millions of years.

In 1996, astronomers announced the discovery of a Jupiter - like planet around this Sun - like star (Marcy and Butler, 1996 — details below), with indications of an even larger planet in an outer orbit.

That's Kepler - 11, a sun - like star around which six planets orbit.

The comet appears to have undergone visible changes, including the changes in the size and number of surface features such as smooth patches, pits, and craters, and the loss of ice vaporized by the Sun or blasted off its surface by the Solar Wind into its tail as well as failing back on the object like snow, so that it appears to shrink, on average, by 25 to 50 centimeters (9.2 to 19.7 inches) with each orbit around the Sun.

The failure, thus far, to find large substellar objects like brown dwarfs or a Jupiter - or Saturn - class planet in a «torch» orbit (closer than the Mercury to Sun distance) around Xi Boötis A — with even the highly sensitive radial - velocity methods of Geoffrey W. Marcy and R. Paul Butler — bodes well for the possibility of Earth - type terrestrial planets around this star (Cumming et al, 1999).

Simplified greatly, an atom looks a bit like our solar system, which has the Sun at its center and planets orbiting around it.

This planet — which orbits Alpha Centauri B — is also the lightest exoplanet ever discovered around a star like our sun.

Like other objects in the Main Asteroid Belt, Ceres moves around the Sun between the orbits of Mars and Jupiter.

After ejection, the moon could either have crashed into another Solar System object (like a neighboring gas giant) or been sent into an elongated orbit around the Sun like a comet or into interstellar space (Boué and Laskar, 2009; and Ker Than, New Scientist, December 4, 2009).

«For example, it used to be widely believed that the sun orbited around the earth because people's experiences, like watching the sunrise and the sunset, provided them with the experiential basis for this to make sense.

The asteroid has a circular orbit around the Sun but at a different speed than the Earth so the motion appears to be like a horse shoe orbit when viewed from Earth.

The argument goes something like this: There are long - term cycles, called Milankovitch cycles, in the Earth's tilt and orbit around the sun.

They are now quite complex and factor in things like; variable output by the sun, variations in the earth's orbit around the sun, greenhouse gases AND dust from volcanoes, greenhouse gases from decay in wetlands and from agriculture (rice paddies are artificial wetlands), differences in the reflectivity («albedo») of different surfaces (grass reflects more sunlight than forest, and ice much more than open water etc.)... and there are many more.
