Orbit of Earth&Moon around Sun

November 16, 2012 § Leave a comment



We all know that the moon orbits the earth. (Well actually they both orbit about their common center of mass (barycenter), which for the earth-moon system lies about 1500km inside the Earths center, so the center of mass of the Earth-Moon system is actually inside the Earth due to the Earth being much much more massive, so we can approximate and say that the moon is orbiting about the Earth). Anyway, just imagining that the Moon orbits about the Earth and then the fact that (similar mass argument for the Earth-Sun system) the Earth orbits about the Sun, what do you think the Earth-Moon orbit around the sun would look like? This is actually a very interesting and hard to visualize question. Just try it.

Will the Moon ever be going backwards around the Sun, relative to Earth, considering that it is going around the Earth, as the Earth goes…

Sunset on Mars

Miss World Security

This is a photo of a sunset on Mars. Awesome huh? Makes you feel so small when you realize how big the universe is… The photo was taken by NASA and you can find more info here    This is what they say about the sunset –

“On May 19, 2005, NASA’s Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover’s 489th Martian day, or sol.

Sunset and twilight images are occasionally acquired by the science team to determine how high into the atmosphere the Martian dust extends, and to look for dust or ice clouds. Other images have shown that the twilight glow remains visible, but increasingly fainter, for up to two hours before sunrise or after sunset. The long Martian twilight (compared to…

Orphan alien planet without a parent star discovered nearby

It's Interesting

Astronomers have discovered a potential “rogue” alien planet wandering alone just 100 light-years from Earth, suggesting that such starless worlds may be extremely common across the galaxy.

The free-floating object, called CFBDSIR2149, is likely a gas giant planet four to seven times more massive than Jupiter, scientists say in a new study unveiled today (Nov. 14). The planet cruises unbound through space relatively close to Earth (in astronomical terms; the Milky Way galaxy is 100,000 light-years wide), perhaps after being booted from its own solar system.

“If this little object is a planet that has been ejected from its native system, it conjures up the striking image of orphaned worlds, drifting in the emptiness of space,” study leader Philippe Delorme, of the Institute of Planetology and Astrophysics of Grenoble in France, said in a statement.

Delorme and his team detected CFBDSIR2149’s infrared signature using the Canada-France-Hawaii Telescope, then…
