Risk––Visitors make comparisons between the risk of asteroid or comet impacts and the risk of more familiar natural disasters such as tsunamis, tornados, earthquakes and volcanic eruptions. As the planets orbit the Sun, they travel at different speeds. Illustrations are accompanied by fact-filled captions that allow even casual readers to gain familiarity with the subject. It has in interactive part of the page where you can learn more about asteroids and comets. It usually refers to the third full moon in a season with four full moons.

The situation changed in 1980 when Uruguayan astronomer Julio Fernández suggested that a comet belt beyond Neptune would be a good source for the short-period comets. Small ones slow down drastically when they hit the atmosphere, and reach a speed of only a few hundred kilometers an hour while they are still many kilometers in the air. With all the various space rocks flying by and into Earth last Friday, perhaps you’ve been wondering about the correct terminology, since a rock from space has different names depending on what it is made of and where it is.

I will be able to define rotation, revolution, gravity, and inertia while explaining how they keep the solar system together. Astrophotographers such as Fred Quintao of Belo Horizonte, Brazil have been following the action nightly. If an asteroid the size of a cruise ship smashed into the ocean, it could cause huge waves capable of drowning coastal cities on two continents."

The middle of June is still within the weaker meteor season, something I sometimes refer to as the ‘meteor doldrums ‘. Forces exerted on the coma by the Sun’s radiation pressure and solar wind cause an enormous, elongated tail to form. Thousands of small meteors enter the atmosphere each day. Unfortunately, the judge for this category was openly hostile to those of us who used computers to do any scientific modelling.

When large bodies such as asteroids and comets strike a planet, they produce an impact crater or impact basin. Most pieces of cometary debris evaporate in the atmosphere, so most meteorites are thought to originate from asteroids. Irons: although they make up about 40% of the meteorites found worldwide, only 2 to 3% of the meteorites are these type. Ultraviolet astronomy is best suited to the study of thermal radiation and spectral emission lines from hot blue stars ( OB stars ) that are very bright in this wave band.

Unlike comets, asteroids tend to come and go unnoticed. If you want to see the effects of very large impacts, you need only go to Arizona to see a large impact crater. My first reaction was to think 'I hope they're not bombs'. Credit: NASA/Ricardo Nunes, http://www.astrosurf.com/nunes. On the rim of the largest crater, named Tüttensee, archaeologists have found Roman relics from about a.d. 200. Jupiter accounts for 0.1%, and all the other planets together are another 0.04%.
