Sentences with phrase «orbital distance»
"Orbital distance" refers to the distance between two objects in space as they orbit around each other, such as planets revolving around the Sun or satellites circling the Earth. It is the measure of how far apart these objects are from each other within their orbit. Full definition

The distance from Altair where an Earth - type planet would be «comfortable» with liquid water is centered around 3.3 AUs — at the outer reaches of the Main Asteroid Belt's orbital distance in the Solar System.
However, owing to the relatively large orbital distances of the currently known NIR stars around Sgr ~ A *, there have been no dynamical measurements of its spin magnitude or orientation.
The range of orientations that lead to transits falls off as orbital distances grow: Small changes in the angle of the planet's orbit become large changes in the apparent position of the planet and star, precluding a transit.
Still, its sun is smaller and cooler than ours, and Gliese 667Cc's orbital distance means it probably receives around 90 percent of the energy we get from the sun.
NASA's Kepler spacecraft has found planet pairs on very similar orbits — with orbital distances differing by as little as 10 percent.
The orbit of an Earth - like planet (with liquid water) around HD 147513 A may be centered around 0.98 AUs — almost the same orbital distance as Earth in the Solar System — with an orbital period around 370 days (or 1.01 years).
At larger planetary orbital distances, the coronagraph is better able to remove the starlight from the area around the planet.
Tracking how long the jet persists could reveal the stellar victim's mass and its original orbital distance, he adds.
Giant stars Aa and Ab are separated by less than the Earth - Sun orbital distance (around 0.73 AU).
This catalogue will include Earth - like planets at intermediate orbital distances, where surface temperatures are moderate.»
In any case, a circumbinary orbital distance from CM Draconis Aab where an Earth - type planet would be comfortable with liquid water would be centered around 0.3 AU, with a «year» of 18 to 35 days.
For perspective, Pluto orbits the sun at an average distance of 40 AU, with a maximum orbital distance of 49 AU.
Kepler - 10c appears to be a super-Earth class planet with 2.2 times Earth's radius, and it orbits the star every 45 days (which is longer than Kepler - 10b's eight - day orbit and so must have a longer orbital distance).
The few confirmed transiting planets at large orbital distances generally only have two observed transits, rather than the standard three transits needed to confirm, and only one of those (KOI - 351 h) is close to Jupiter - sized.
The «non-detections» place upper limits on the number of certain types of planets; that is, if there were any more planets of a certain mass or orbital distance then these surveys would have found them.
As a giant star, the Sun will become as much as 5,000 times brighter, and its radius will expand as far out as the Earth's current orbital distance of one AU.
Their simulations suggest that at least one planet in the one to two Earth - mass range could have formed within orbital distances of 0.5 to 1.5 AUs around both heavy - element - rich stars; of particularly note, the simulations frequently generated a Earth - like planet in or near Star B's habitable zone (where liquid water could exist on the planet's surface).
Currently, the water zones for either Capella Aa or Ab are farther out than the average orbital distance between these two stars.
The magnitude of the shift in the starlight's wavelength — on the order of quadrillionths of a meter — together with the period of the wobble can be used to determine an exoplanet's mass and orbital distance from its star.
