This orbital program does not take into account observational errors, gravitational influences or comet out gassing.
Therefore predictions such as this cannot be relied on to give accurate figures.

Comet 55P/Tempel-Tuttle
Permalink  
 


Ernst Wilhelm Liebrecht Tempel (Marseille, France) discovered this comet on 1865 December 19. It was then in the evening sky near the star Beta Ursa Majoris. He described it as a circular object, with a central condensation and a tail 30 arc minutes long. Horace Parnell Tuttle (Harvard College Observatory, Cambridge, Massachusetts) independently discovered this comet on 1866 January 6.

The comet's best apparition was that of 1366 when it passed 0.0229 AU from Earth (2.1 million miles and 3.4 million kilometres)--marking the third closest approach of any comet to our planet in recorded history. Astronomers have suggested the total brightness may then have reached magnitude 3. The comet passed 0.0644 AU from Earth in 1699, which marked the 18th closest approach of a comet to Earth. The brightness may then have reached 4th magnitude.

Hum,
it should be a good return.
(The Earth's distance from Sun is about 146 million km)

"The most recent storm occurred in 1966 after Temple-Tuttle had returned. In 1965 calculations revealed that the comet passed closer to the Earth's orbit than on any occasion since 1833. On November the 17th 1966 a storm occurred that rivalled the great storms of 1799 and 1833. Within two hours, observed rates increased from around 40 per hour to around 40 per second ! When the storm had finished it was calculated that at the peak rate 150,000 meteors were seen for around 20 minutes."

I was playing around with your 3D orbit and I found that on November 22, 2097 Temple-Tuttle will be only 35,903,520km from earth!     :smile:
