What is an extrasolar planet quizlet? What is an extrasolar planet? A planet that orbits a star that is not our own Sun. (“Extrasolar” means “beyond the Sun.”) What is meant by an extrasolar planet? extrasolar planet, also called exoplanet, any...
Which planet has the greatest uncompressed density? Mercury is the smallest planet in the solar system with a radius of 1520 mi (2440 km). It is smaller than Mars, but bigger than our Moon. It is smaller than Jupiter’s moon Ganymede...
How do the terrestrial planets compare to the Jovian planets quizlet? Jovian planets are larger in size than terrestrial planets. Jovian planets are larger in mass than terrestrial planets. Jovian planets orbit farther from the Sun than terrestrial planets. The solar...
Why did planetesimals grow slowly in the inner solar system and significantly faster in the outer solar system? Why did planetesimals grow slowly in the inner Solar System and significantly faster in the outer Solar System? In the outer Solar System,...
How did the solar nebula get cleared away? Eventually, 4 effects clear away the nebula: the Sun’s radiation pressure, the solar wind, the gravitation of the individual planets, and close encounters between planets and planetessimals. METEORS, COMETS, ASTEROIDS are left as...

What is a stellar size black hole? A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are...
What is Stephen Hawking’s black hole theory? In 1976, Hawking suggested that, as black holes evaporate, they destroy information about what had formed them. That idea goes against a fundamental law of quantum mechanics which states any process in physics can...
What is Stephen Hawking’s most famous theory? In 1974 Hawking proposed that, in accordance with the predictions of quantum theory, black holes emit subatomic particles until they exhaust their energy and finally explode. What does The Theory of Everything explain? The...
