It's the area in between the fourth planet, Mars, and the fifth, Jupiter, that's important. An astronomical unit (AU) is the distance between the Earth and the sun, which is about 150 million kilometers -- astronomers use this distance as a ruler to measure other distances within the ...
How does the Sun's diameter compare with the distance between Earth and the Sun? How does the sun's diameter compare with the distance between the earth and the sun? How many times could the planet Earth fit inside Jupiter? Take the radius of the Earth to be 6,371 km and the ra...
Hubble used the light curves of the Cepheid variables to measure their distances from Earth and found that they were much farther away than the known limits of the Milky Way. Therefore, these spiral nebulae were indeed other galaxies outside our own. There are still many mysteries surrounding ...
Hubble drifts over Earth after its release on May 19, 2009, by the crew of the Space Shuttle Atlantis. The crew had performed all planned tasks over the course of five spacewalks, making the Servicing Mission 4 (SM4), the fifth astronaut visit to the Hubble Space Telescope, an unqualified...
How Earth could die: Artist’s conception of a Jupiter-size rogue planet. Image: Wikipedia 2. The approach of a wandering star Timeframe: possibly within the next million years If a rogue planet can do that much damage, imagine what a star could do. ...
How large is Jupiter's exosphere? How many moons do the gas planets have? How many rogue planets are in the Milky Way? How much does Jupiter weigh? How many moons does Eris have? How many solar masses is a black hole? How many astronomiacl units is the Kuiper belt from the sun? Ho...
Astrology is still given short shrift when not accused of intellectual heresy. Linear thinking dominates and it's oriented towards simplistic formulae. These narrow constructs are used to control the masses. Linear thought pivots on direct cause and effect relationships. These typically use a ...
At least one classification scheme distinguishes the planets in our solar system with theirposition relative to Earth. Under this scheme, "inferior" planets (those inside Earth's orbit) are Mercury and Venus. "Superior" planets (those outside Earth's orbit) are Mars, Jupiter, Saturn, Uranus ...
Earth’s orbit would not be changed if Jupiter were a small star (the mass would be 100 current Jupiter masses). Jupiter and the Sun would orbit each other around a barrycenter (a common center of mass) this would be about one-half of an AU (AU=earth-sun distance...
Giant young star is growing by 2 Jupiter masses every year, new study shows Launch of Australia's 1st homegrown orbital rocket delayed indefinitely due to payload fairing issue NASA resurrects Voyager 1 interstellar spacecraft's thrusters after 20 years: 'These thrusters were considered dead' ...
