Planets in a sentence

Likewise, dwarf planets in the asteroid belt and Kuiper belt should be considered planets according to Stern. citation Captured planets Free-floating planets in stellar clusters have similar velocities to the stars and so can be recaptured.

Based on how frequently planets orbit stars and the spacing between planets, the researchers guessed that only 13 of the dips could have come from regularly orbiting planets.

However, this does not give estimates for the number of extrasolar terrestrial planets, because there are planets as small as Earth that have been shown to be gas planets (see KOI-314c ).

Other celestial bodies (planets, moons) The appearance of plate tectonics on terrestrial planets is related to planetary mass, with more massive planets than Earth expected to exhibit plate tectonics.

Stars with a higher metallicity than the Sun are more likely to have planets, especially giant planets, than stars with lower metallicity. citation Some planets orbit one member of a binary star system, Schwarz, Richard.

The displays include all about planets, voyager distance display, constellation light tracing, weight on other planets, astronaut cutout, astronaut display, and the human gyro exhibit.

On the 21st, the planets will appear so close that a pinkie finger at arm’s length will easily cover both planets in the sky.

Since the Solar System is flat and all the planets orbit the Sun on the same plane—more or less—you’ll only ever find planets on the ecliptic.

The Galactic Empire no longer has a hold over many planets, but there are still Imperial loyalists who lead factions that dominate some planets, like Nevarro.

To the best of our knowledge rocky planets are formed around a metallic core, although the hypothesis of planets has been floated around.

Although it is known today that the planets revolve around the sun, the same terms continue to be used in order to describe the movement of the planets in relation to the stars as they are observed from Earth.

Although planets can sometimes be mistaken for stars as one observes the night sky, the planets actually change position from night to night in relation to the stars.

A real orrery would be more accurate and include more planets, and would perhaps make the planets rotate as well.

Astronomers refer to a region of minor planets beyond Neptune as the " Kuiper belt ", since Kuiper had suggested that such small planets or comets may have formed there.

Encyclopaedia Britannica, 1968, vol. 2, p. 645 Theories of this kind predicted paths of the planets moderately well, until Johannes Kepler was able to show that the motions of planets were elliptical motions.

Even though this research has greatly restricted the possible properties of planets around Barnard's Star, it has not ruled them out completely; terrestrial planets would be difficult to detect.

Fleets of microbial capsules can be aimed at clusters of new stars in star-forming clouds, where they may land on planets or captured by asteroids and comets and later delivered to planets.

Formation and migration main seeAlso Earth and its neighbor planets may have formed from fragments of planets after collisions with Jupiter destroyed those super-Earths near the Sun.

Giant planets are also sometimes called jovian planets, after Jupiter.

He also found the object did not change its position relative to the fixed stars over several months, as all planets did in their periodic orbital motions, even the outer planets for which no daily parallax was detectable.
