Is Comet Swift-Tuttle part of solar system?
Swift-Tuttle, whose nucleus is 16 miles (26 kilometers) wide, is the largest solar system object to pass close to Earth repeatedly, NASA has said, and researchers once thought it was likely to hit Earth in 2126 — but the last time it passed Earth, in 1992, astronomers took more precise measurements and calculated that …
How long does it take Swift-Tuttle to orbit the sun?
133 years
Comet Swift–Tuttle/Orbital period
Comet Swift-Tuttle has a very eccentric – oblong – orbit that takes this comet outside the orbit of Pluto when farthest from the sun, and inside the Earth’s orbit when closest to the sun. It orbits the sun in a period of about 133 years.
Who discovered the Swift-Tuttle comet?
Horace Parnell Tuttle
Lewis A. Swift
Comet Swift–Tuttle/Discoverers
A periodic comet, the parent of the Perseid meteor shower, independently discovered in 1862 July by the American astronomers Lewis Swift (1820–1913) and Horace Parnell Tuttle (1837–1923). It reached magnitude +2 and showed a tail 25–30 ° long in 1862 August.
What happens if a comet hits the sun?
If a comet is big enough and passes close enough, the steep fall into the sun’s gravity would accelerate it to more than 600 kilometres per second. The momentum propelled by the comet could even make the sun ring like a bell with subsequent sun-quakes echoing through the solar atmosphere.
What will happen if a comet gets closer to the sun?
As the comet gets closer to the Sun, some of the ice starts to melt and boil off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. The coma is lit by the Sun. The sunlight also pushes this material into the beautiful brightly lit tail of the comet.
Is Eris a comet?

Where did Comet Hyakutake come from?
The comet was discovered on 30 January 1996, by Yuji Hyakutake, an amateur astronomer from southern Japan. He had been searching for comets for years and had moved to Kagoshima Prefecture partly for the dark skies in nearby rural areas.
Where is Swift Tuttle now?
Comet 109P/Swift-Tuttle is currently in the constellation of Hydra.
What is the fastest comet ever recorded?
At a breathtaking speed of over 175 000 kilometres per hour, Borisov is one of the fastest comets ever seen. It is only the second interstellar object known to have passed through the Solar System. In October 2019, Hubble observed the comet at a distance of approximately 420 million kilometres from Earth.
Do asteroids ever hit the Sun?
No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.
How long is the orbital period of Comet Swift-Tuttle?
Comet Swift–Tuttle (formally designated 109P/Swift–Tuttle) is a periodic comet with a current ( osculating) orbital period of 133 years. It fits the classical definition of a Halley-type comet with a period between 20 and 200 years.
Is the Comet Swift Tuttle responsible for the Perseids meteor shower?
In fact, debris from Comet Swift-Tuttle is responsible for the Perseids meteor shower visible every July and August. Comet Swift-Tuttle is expected to make an impressive pass near the earth in the year 2126, possibly similar to Comet Hyakutake this year or Comet Hale-Bopp next year.
Who was the first person to discover the comet?
It was independently discovered by Lewis Swift on July 16, 1862 and by Horace Parnell Tuttle on July 19, 1862. It has a well determined orbit and has a comet nucleus 26 km in diameter. Chinese records indicate that, in 188, the comet reached apparent magnitude 0.1.
