Comet Swift-Tuttle is the largest object known to repeatedly pass byEarth; its nucleus is about 16 miles (26 kilometers) wide. It last passed near Earth during its orbit aroundthe sunin 1992, and the next time will be in 2126. When you sit back to watch a meteor shower, you're actu...
I set the camera on a tripod (三脚架) in my garden, and then I began the countdown to 4:00 a. m., when the comet was scheduled to appear. I recall thinking, “If everything goes as planned, the photo will show the comet as a line of light moving across a background of stars...

Halley's Comet was first discovered by Edmond Halley in the 1700s. His discovery was based on his observation of a pattern in the historical record of comet appearances, leading him to predict the next pass of the comet near Earth.

This year, the Orionid meteor shower will peak on Oct. 21. In moonless skies, viewers will be able to see about 23 meteors per hour during this time, NASA said. Orionid meteors appear every year when Earth travels through an area of space littered with debris from Halley's Comet.NASA/...

The Perseid shower is associated with the Swift-Tuttle comet. When the tiny bits of dust trains strike Earth’s upper atmosphere, friction with the air causes each particle to heat and burn up. We see the result as a meteor.See more facts about meteor showers. ...
The source of the meteors is an asteroid, it is speculated that Phaethon is actually a comet that has lost its ice and dust and therefore the meteors are it crumbling under the stress of orbitingThe radiant point of the meteor shower, the point at which they can be seen is by the ...
