Sentences with phrase «exerted by the planets»

The planet — Proxima b — was discovered by astronomers who spent years looking for signs of the tiny gravitational tug exerted by a planet on its star, after spotting hints of such disruption in 2013.

Not exact matches

Because the planets are bunched, they exert a small gravitational pull when they pass by each other.

Known as the Doppler method, it measures the gravitational tug exerted on a star by a planet — a planet that could not be seen directly because it would be lost in the glare of its star.

The planet was found with the radial velocity method, a planet - hunting technique that relies upon slight variations in the velocity of a star to determine the gravitational pull exerted by nearby planets that are too faint to observe directly with a telescope.

A planet's angular momentum equals the mass of an object multiplied by its distance from the Sun, and corresponds with the force that the planet exerts on the overall system's spin.

For example, Earth raises tides on the moon and vice versa, and the planets beyond Uranus were discovered by the gravitational perturbations they exerted on the seven planets that had already been discovered.

«Ceres or ammonia - rich material from the outer solar system could have been implanted in the Asteroid Belt as a result of orbital perturbations exerted by the giant planets» early in the solar system's history, De Sanctis says.

Astronomers could discover a plethora of planets around binary star systems ¬ - stars that rotate around each other — by measuring with high precision how stars move around each other, looking for disturbances exerted by possible exoplanets.

These massive worlds would exert a herculean tidal force on any small objects in their vicinity, and many would be ripped to shreds — like Comet Shoemaker - Levy 9 that was pulled apart by Jupiter's gravity and then spectacularly impacted the planet in 1994.

The end of the bipolar world with the collapse of the Soviet Union in 1989 made to materialize the hegemonic situation exerted by the United States in the world that is threatened today by its economic weakness and the economic and military rise of China that has highlighted in the geopolitical world by great political influence, military and economic in the Asian and international scene thanks to the great extension of its territory (ranked third in territorial dimension on the planet), high number of inhabitants (about 1.3 billion, most populous in the world) and the dynamism of its economy (the economy is currently showing the highest growth rates on the planet).

It's also disappointing that Bioware seem to have missed a beat, because while you're building up these forces feels like you're going to be the one that decides what to do with all these assets when the times comes, able to effect the games outcome by careful use of the fleets and troops that you've acquired through missions, planet scanning and more, yet there's only one moment in the entire game you even get to see your assets, and you certainly never get to exert any control over them.

But if you accept that the greenhouse effect is real, and that CO2 is a GHG, and that CO2 has increased (along with other GHGs), you have to accept the merit of my point: that solar, volcanoes, ocean currents and other natural variations do their thing, they vary, but GHGs exert a steady, constant upward forcing on temperature, which upward forcing is only offset by increased heat losses to space from a warmer planet.

But is there a chance that solar activity is affected by tidal forces exerted on the sun by Jupiter and the other planets?

A planet's angular momentum equals the mass of an object multiplied by its distance from the sun, and corresponds with the force that the planet exerts on the overall system's spin.

This might imply the presence of very large planets close by, or a high number of planets in the solar system, or even multiple other solar systems which are close enough to exert significant gravitational attraction.
