What is the longest orbital period of a comet?

70,000 years As far as the longest period comets go, the current leaders are Comet Hyakutake with an orbital period of 70,000 years, Comet C/2006 P1 with an orbital period of about 92,000 years and Comet West with an orbital period of about 250,000 years. Subsequently, what dwarf planet has the longest orbital period? Its surface is one of the reddest among Solar System objects. To within estimated uncertainties, Sedna is tied with Ceres as the largest planetoid not known to have a moon. 90377 Sedna. Discovery Semi-major axis 506 AU (75.7 Tm) Eccentricity 0.8496 Orbital period (sidereal) 11390 yr (barycentric) Average orbital speed 1.04 km/s 31 more rows

You can also ask what does a longer orbital period mean?

Result: a more distant planet must orbit the Sun at a lower average orbital speed. Slower orbital speed and a larger orbit mean that its orbital period must be longer! What's the farthest planet discovered? Astronomers have discovered one of the most distant planets known, a gas giant about 13,000 light-years from Earth, called OGLE-2014-BLG-0124L. The planet was discovered using a technique called microlensing, and the help of NASA's Spitzer Space Telescope and the Optical Gravitational Lensing Experiment, or OGLE.

What comet passed Earth in 1996?

Comet Hyakutake Comet Hyakutake was a naked-eye comet that made its closest approach to Earth in March 1996 after being discovered just two months earlier. First spotted through binoculars, the comet remained visible to the naked eye for three months and was the brightest comet seen in 20 years. Is Eris or Pluto bigger? Eris is one of the largest known dwarf planets in our solar system. It's about the same size as Pluto but is three times farther from the Sun. At first, Eris appeared to be larger than Pluto.
