Sentences with phrase «orbital radius»
The phrase "orbital radius" refers to the distance between an object in space, like a planet or a satellite, and the center of the celestial body it is orbiting around. It helps us understand how far away something is in space. Full definition
«This is the widest range of orbital radii of any planetary system known,» Marois told New Scientist.

For an object so big, these flashes are extremely short, implying a radiating surface about the same as a sphere with orbital radius of Jupiter.
They eliminated those with orbital radii less than one tenth that of Earth's, because at that distance moon systems might not remain in stable orbits around their planets on billion - year timescales.
The planet candidates, on the other hand, reside at orbital radii around 15 au, where disk observations have been unreliable until recently.
The emission fits a model with a grain temperature of 40 K, indicating a minimum orbital radius of 60 AU from the host star.
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).
Objects many orbital radii away (and confined to the plane of the solar fragment orbit) would orbit the barycenter in the normal fashion.
The planet is extremely close to its star — its orbital radius is only about three times the radius of the star — and the scientists have estimated that its surface temperatures may be as high as 3,000 degrees Kelvin, or more than 5,000 degrees Fahrenheit.
A simulation (Wolf & D'Angelo 2005) of ALMA observations at 950 GHz of a disc shows an embedded protoplanet of 1 Jupiter Mass around a 0.5 Solar Mass star (orbital radius: 5AU).
We will compare the exoplanets» dominant atmospheric components as a function of host star properties (composition and mass) and planet properties (mass, density, irradiation, orbital radius) to trends from the planet formation models and the Genesis database we developed (Projects 3.2 and 3.3).
Based on the star's mass and the period of the shift, we can also calculate the planet's orbital radius.
The radius corresponds to 10 times the orbital radius of Neptune in our solar system.
However, the motions of the objects outside the orbital radius by only a small amount would again behave in a fashion I can not theoretically explain.
