Sentences with phrase «than its planet spins»

If a moon revolves more slowly than its planet spins — as both Deimos and our moon do — it moves outward.

But if a moon revolves faster than the planet spins — as Phobos does — it moves inward and the planet's gravity tears it to pieces, which smash into the surface below.

Not exact matches

The surprise was that the light coming from it pulsed in brightness by a factor of 10 every 7.3 hours, suggesting both that it is spinning rapidly and is 10 times longer than it is wide — more elongated than anything known among our planets.

The feeble glow of microwaves from the sun is absorbed by our air on the way down, anyway, so unless the core somehow also strips off Earth's atmosphere — in which case we have bigger problems than solar radiation — we should be safe enough from microwaves if our planet's center stops spinning.

Song calculates that the solid inner core spins just slightly faster per year than the rest of the planet, a difference that adds up to an extra revolution every 1,000 years or so.

The glow seemed consistent with the size and shape of the matter needed to make ngc 5907 spin the way it does, so astronomers hoped that this might be the first sign that the dark halos were made of ordinary stars and planets — albeit faint ones — rather than exotic, yet - to - be discovered particles.

A near miss with a pre-existing moonlet is more effective at producing capture than is actual collision — a larger prograde momentum (one in the direction of the planet's spin) is transferred to the captured moon.

The different Q values also allow the planets to re-align their orbits with the spin of the star (so that the orbital plane is perpendicular to the star's spin axis) on a timescale shorter than the orbital period decay, thus explaining why there are many «aligned» hot Jupiters.

In other cases, when a solar system contains more than 3 massive Jupiter - like planets, the orbits become unstable by the gravity of these planets and some of them may spin out the planetary system.

Although Jupiter is ten times wider than Earth, it manages to spin around 2.5 times as fast as our little planet.

If planets and moons evolved from swirling dust clouds as is commonly taught, each of the almost 200 known moons in the solar system should orbit its planet in the same direction as the planet spins, but more than 30 moons have backward orbits.e Furthermore, Jupiter, Saturn, Uranus, and Neptune have moons orbiting in both directions.

What might happen, for instance, if an Earth - like planet rotated on its spin axis very slowly (a full rotation in 128 days rather than 24 hours?)

Dawn of the Planet of the Apes is director Matt Reeves sequel to Rupert Wyatt's prequel, which was in - turn a reboot of a franchise born in the late sixties that went on to spawn more than 5 spin - offs as well as a television series.

Secondly, most of the ice that will melt and contribute to sea - level rise is currently closer to the spin axis than it would be if it were uniformly distributed across the surface of the planet... so, I am not sure it would lead to a shortening of the LOD but I am willing to be persuaded otherwise.

But that would require some sort of spin orbit coupling stronger than the tidal forces between planets can account for, right?

And your spin offs onto other planets are so far into the future as to be little more than a wishlist.

This all comes up when thinking about whether a fast spinning planet cools differently than a slow one (like the moon).

The tilt has long confounded astronomers because of the way the planets formed: as a spinning cloud slowly collapsing first into a disk and then into objects orbiting a central star, according to Caltech (who can say this better than I can):

It's really pretty hard to put a positive spin on what's happening down in the Gulf of Mexico, or really even see a good outcome, but in an interesting interview on the potential effects of the spill over at OnEarth fisheries expert Daniel Pauly from the University of British Columbia points out one small thing that may make cleaning up this spill easier than the iconic Exxon Valdez: WATCH VIDEO: Planet 100 - How to Clean An Oil Spill?
