It was first discovered in 1995 by both Alan Hale and Thomas Bopp, after whom it was named. It was first visible in mid 1996, but did not reach its brightest until […]Continue reading Continue reading

The Trojans and Greeks

As was recently discussed in class, there are two clusters of asteroids ahead of and behind Jupiter known as the “Trojans” and the “Greeks”. The first one to be discovered was an asteroid now known as “Achilles”, a hero who fought on the Greek side of the Trojan War. The Greeks are all slightly ahead […]Continue reading Continue reading

Ida and Dactyl

243 Ida is a 56 km long asteroid orbiting in the main asteroid belt with a number of notable features. Ida is an S-type asteroid, or stony asteroid, and is mostly composed of rock and iron from accretion during early solar system formation. Ida was a subject of study by the Galileo spacecraft in 1993, … Continue reading Ida and Dactyl Continue reading Continue reading

Comet Shoemaker-Levy 9

In 1994, one year after its discovery, the fragmented remains of Comet Shoemaker-Levy 9 crashed into Jupiter’s upper atmosphere in a sequence of 23 large impacts, each releasing the energy equivalent of 25,000 megatons of TNT, more than one million times as much energy as released by the nuclear bomb dropped on Hiroshima. Orbital analysis … Continue reading Comet Shoemaker-Levy 9 Continue reading Continue reading

Asteroids: Death, or Life?

Just hitching a ride Most people don’t think of asteroids as the bringer of life to Earth. Actually, for many, it’s the exact opposite. When someone says asteroids many people automatically think about mass extinctions, specifically the extinction of the dinosaurs (which was caused by a large asteroid). However, there is a theory called panspermia which […] Continue reading Continue reading

Fun Facts about Titan

Out of all the moons in our solar system, my favorite one would have to be Titan. Titan is the second largest moon in our solar system, second only to that fat piece of lard Ganymede. However, Titan, has something that Ganymede doesn’t and that is an “earth like cycle of liquids flowing across its […] Continue reading Continue reading

Comets and stuff

For blog 7 I’ve decided to write about comets. Comets, according to space.com is “an icy body that releases gas or dust”(space.com) Astronomers believe that comets are leftovers of the gas, dust, ice, and rocks that originally formed our solar system. It is believed that comets carried some of the water and organic molecules that […] Continue reading Continue reading

Halley’s Comet

Halley’s Comet is visible from Earth every 75-76 years. It is the only known short-period comet (a comet that has an orbital period of less than 200 years) that is visible to the naked eye. Halley most recently visited the inner parts … Continue reading Continue reading Continue reading

The Stardust Mission

Missions that deliberately bring back extraterrestrial material to Earth are rare. The NASA Stardust, a probe that launched in  1999, sought to collect dust samples from the comet Wild 2’s tail. Prior to the mission, experts believed that the dust in comets’ tails would be pre-solar particles. Instead, what they found from the particles retrieved […] Continue reading Continue reading
