Perseids Meteor Shower -- Like most meteor showers, the Perseids are caused by comet debris. As comets enter the inner solar system, they are warmed by the sun and peppered by the solar wind, which produces the familar tails that stretch across the night sky when a bright comet is close to Earth. Comet tails are made of tiny pieces of ice, dust, and rock which are spewed into interplanetary space as they bubble off the comet's nucleus. When Earth encounters these particles on its...

When the Earth moves through the meteor stream, the meteor shower is visible. The Leonids get their name from usually making their appearance in or near the constellation Leo. The Leonids are famous because their meteor showers,...

Its most recent apparition was in 1998, when it reached perihelion on February 28. As expected, it showed little activity, and only a small tail. However, further inspection shows that this comet is more interesting than the first glance suggests. Its orbit is oriented in such a way that the comet makes a...
