The sections in the page have an overall main heading then smaller font for different topics. The meteors in a shower are in fact travelling on parallel lines, they just seem to radiate from one point, as parallel train tracks appear to radiate from one point in the distance. S class asteroids of the inner belt, closer to Mars, consist mostly of stone and iron.

The comet itself was still effectively in "deep freeze." Above: Astronomers have been counting sunspots for centuries. By the end of the 19th century there were several hundred. Verschuur: This photo of the Moon shows an amazing density of impact craters. It entered Earth's atmosphere at a speed of 27,000 miles per hour (43,000 km/h) and broke up at an altitude of 43 miles (70 km). Some scientists believe that some comets have life like earth because some comets have life organic molecules and water.

A large asteroid named Adonis passed within 186,000 miles of Earth. Comets are also chunks of rock, but they have ice mixed in as well. Provides information on detecting meteors by radio. First is the Oort cloud, located much further from the solar system, and the second is the Kuiper belt, located just beyond the orbit of Neptune.

The 99 meteorites from Mars exhibit precise elemental and isotopic compositions similar to rocks and atmosphere gases analyzed by spacecraft on Mars, starting with the Viking lander in 1976. Even if you know this, what you might not know is that there is a meteor shower worth-watching almost every month. How likely is it that our planet could be hit by a large asteroid or comet? You’re currently on our quick space facts page where you’ll learn loads of quick facts about our universe and the solar system we live in.

After around 500 passes, they lose most of their ice and gas content and eventually turn into something close to an asteroid. From Telescopes to Software Outer Space Astronomy sites to help you understand the planets, the stars and other things far out in the sky. NEAR (now renamed "NEAR-Shoemaker") entered orbit around 433 Eros (right) in January 1999 and returned a wealth of images and data. I'm not on the spacecraft science team, so I'm not sure what the future plans are, if any. www.nasa.gov/epoxi Nick_Howes: Has this mission, along with the previous 5 encounter missions given us any further insights into how/if we should improve the NEO monitoring and our possible response to a potential Earth impacting object?

A meteorite located after a witnessed descent is called a fall. And notice the names given to June's "2002 MN" asteroid (see above) and July's "2002 NT7" asteroid - are these references to Microsoft Network (MN) and Windows NT (NT)? The Earth orbits the Sun in a sort of cosmic shooting gallery, subject to impacts from comets and asteroids. Theories on the generation of these sounds may partially explain them. PaulAFelty: If a Hartley-2 sized object made up of the same composition, hit the earth at it's given velocity, what kind of crater are we talking about here?

All asteroids with orbits so eccentric that they cross Earth's orbit are called 'Apollo asteroids', 'Amors' approach the Earth but do not cross Earth's orbit. The airburst of the 17-meter Russia asteroid released as much energy as nearly 500 kilotons of TNT 20-30 kilometers above the surface, knocking out windows for many kilometers around. A meteor is a rock in space that is less than a meter in diameter. Made by Beakus for the Royal Observatory Greenwich, the animation is one in a series of explainers behind the European Space Agency’s Rosetta spacecraft and Philae lander mission.

The meteors are medium speed (27 miles [43 km] per second); they tend to be faint, and few leave trains. This is why asteroids are also called Minor Planets. The planets in our Solar System move on steady orbits around the Sun. Also known as the southern lights, this is an atmospheric phenomenon that displays a diffuse glow in the sky in the southern hemisphere. A second minor planet – Pallas – was found by Wilhelm Olbers in 1802.

Let me know if you're ever searching for a particular topic. On the other hand, the rest of the comets can take more than a thousand years to finish their orbit! “In 1682 another great comet appeared. Stardust continued on its journey after dropping off the sample from Wild 2, and visited the comet Tempel 1 (see below) to check on the "damage" caused by another spacecraft. The predawn nights from the end of July to mid-August are typically very rich in meteors, and the show has already begun.
