Due to the comet's very small minimum orbit intersection distance with Earth, around 0.015 AU (2.2 million km) away, it is theorized that this comet is a potential parent body of a meteor shower that should appear 21 August of each year from a radiant in the direction of the constellation Hydrus.

At the shorter orbital period extreme, Encke's Comet has an orbit that does not reach the orbit of Jupiter, and is known as an Encke-type comet. Short-period comets with orbital periods less than 20 years and low inclinations (up to 30 degrees) to the ecliptic are called traditional Jupiter-family comets (JFCs).
However, in April 1996 the comet passed within 0.77 au of Jupiter, close enough for its orbit to be measurably affected by the planet's gravity. [37] The comet's orbit was shortened considerably to a period of roughly 2,399 years, [4] and it will next return to the inner Solar System around the year 4385. [8]
This is a list of comets (bodies that travel in elliptical, parabolic, and sometimes hyperbolic orbits and display a tail behind them) listed by type. Comets are sorted into four categories: periodic comets (e.g. Halley's Comet), non-periodic comets (e.g. Comet Hale–Bopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...
Its orbit around the Sun is highly elliptical, with an orbital eccentricity of 0.967 (with 0 being a circle and 1 being a parabolic trajectory). The perihelion, the point in the comet's orbit when it is nearest the Sun, is 0.59 au (88 million km). This is between the orbits of Mercury and Venus.
It's steadily moving away from the Earth after reaching its closest point on Saturday. If you miss this chance, the comet won't return for 80,000 years. Social media users share images of Comet C ...
Astronomers have been discovering weakly hyperbolic comets that were perturbed out of the Oort Cloud since the mid-1800s. Prior to finding a well-determined orbit for comets, the JPL Small-Body Database and the Minor Planet Center list comet orbits as having an assumed eccentricity of 1.0. (This is the eccentricity of a parabolic trajectory ...
Subsequent to 4479, the orbital evolution of the comet is more difficult to predict; the probability of Earth impact per orbit is estimated as 2 × 10 −8 (0.000002%). [7] Comet Swift–Tuttle is by far the largest near-Earth object (Apollo or Aten asteroid or short-period comet) to cross Earth's orbit and make repeated close approaches to ...
