When was Comet Swift-Tuttle last seen?
1992
Comet Swift-Tuttle was last seen in 1992, an unspectacular pass through the inner solar system that required binoculars to enjoy. Prior to that, it had last been seen in the year it was “discovered” by American astronomers Lewis Swift and Horace Tuttle, 1862.
Where is the Swift-Tuttle comet now?
constellation of Hydra
Comet 109P/Swift-Tuttle is currently in the constellation of Hydra.
How fast is Comet Swift-Tuttle?
And its dust and debris, which create the Perseid meteor shower as they burn up in Earth’s atmosphere, are traveling quickly, too — at around 37 miles (59 km) per second.
Will Halley’s comet hit the Earth?
It will be decades until Halley’s gets close to Earth again in 2061, but in the meantime, you can see its remnants every year. The Orionid meteor shower, which is spawned by Halley’s fragments, occurs annually in October.
Why is Tempel Tuttle famous?
Tempel-Tuttle last reached perihelion (closest approach to the sun) in 1998 and will return again in 2031. The pieces of space debris that interact with our atmosphere to create the Leonids meteor shower originate from Tempel-Tuttle.

How often does the Perseid meteor shower occur?
The Perseids are one of the brighter meteor showers of the year. They occur every year between July 17 and August 24 and tend to peak around August 9-13.
How big was the comet that killed the dinosaurs?
The asteroid was about 7.5 miles (12 kilometers) in diameter and was traveling about 27,000 mph (43,000 km/h) when it created a 124-mile-wide (200 km) scar on the planet’s surface, said Sean Gulick, a research professor at the University of Texas Institute for Geophysics, who led the study.
How old is Halley’s comet?
Scientists calculate that an average periodic comet lives to complete about 1,000 trips around the Sun. Halley has been in its present orbit for at least 16,000 years, but it has shown no obvious signs of aging in its recorded appearances.
What type of comet is Swift Tuttle?
Comet Swift–Tuttle (formally designated 109P/Swift–Tuttle) is a large periodic comet with a 1995 ( osculating) orbital period of 133 years that is in a 1:11 orbital resonance with Jupiter. It fits the classical definition of a Halley-type comet with an orbital period between 20 and 200 years.
Who discovered comet 109P/Swift-Tuttle?
Comet Swift-Tuttle was discovered in 1862 independently by both Lewis Swift and Horace Tuttle. Comet 109P/Swift-Tuttle takes 133 years to orbit the Sun once.
What is the period of Swift Tuttle?
Comet Swift–Tuttle (formally designated 109P/Swift–Tuttle) is a periodic comet with a current (osculating) orbital period of 133 years.
Will Comet Swift-Tuttle ever hit Earth?
In 1996, the long-term possibility of Comet Swift–Tuttle impacting Earth was compared to 433 Eros and about 3000 other kilometer-sized objects of concern. ^ v = 42.1219 √ 1/ r − 0.5/ a, where r is the distance from the Sun, and a is the semimajor axis.
