Despite being a short-period comet
, with an orbital period of about 5 years, it was only reobserved in 2003, when it appeared stellar.
The Eta Aquarids is one of two meteor showers created by debris from Halley's Comet, a short-period comet
visible from earth every 74 to 79 years.
Virtually any short-period comet
among the 100 or so not currently coming near the Earth could become dangerous after a close passage by Jupiter."
Halley Schmidt, 15-year-old amateur astronomer, was named after the famous short-period comet
by her astronomer parents, Linda and Theo.
It was the first short-period comet
known and, indeed, to this day no comet has been discovered with a smaller orbit.
But occasionally a cometary nucleus leaves its fellows and plummets into the inner solar system, where it may come close enough to the Sun for us to designate it as a long-period comet; or else it might make a close pass by one or more of the major planets, and have its orbit progressively altered, so that eventually we describe it as a short-period comet
Marsden, appeared on MPEC 2000-Y47, together with orbital elements showing it to be a short-period comet
. Further to IAUC 7552, J.
However, the value measured in a short-period comet
, 103P/Hartley 2, has a very Earth-like value.
Dr Miles opened by summarising the physical characteristics of comet 17P/Holmes, explaining that it was a short-period comet
of the Jupiter family.

near the Sun', A&A, 445, 759 (2006)
They originate from the unusually short-period comet
2P/Encke and other objects that seem to be ancient Encke breakup products, including the dormant, asteroid-like comet 2004 [TG.sub.10].
These originate from the asteroid-like object 2003 EH1, a dormant Jupiter-family short-period comet
that suff ered a breakup about 500 years ago.
