David Levy and Gene Shoemaker met when Levy was a young amateur astronomer and contacted Shoemaker to assist with his comet observations. Shoemaker recognized Levy's potential and mentored him in astronomy, leading to a successful collaboration on discovering comets together.
Every comet is different. We divide comets into two broad categories; "short period" comets, with periods less than about 200 years, and long-period comets, with longer intervals between passes. Since our recorded astronomical history only goes back about 400 years, there are probably a great number of long-period comets floating far out in space and only just now starting to fall into the inner solar system.
That depends on what you call 'long' or 'short'. Halley's period is in the neighborhood of 75 years, give or take a few years. Since that's short enough for two perihelions to occur within a single human lifetime, I guess it ought to be considered a short period.
Yes, as long as they are kept cold and sterile - they will only be viable for a short period of time.
Long-period comets have periods of over 200 years.The longest would probably be somewhere around a million years (comparable to the orbital periods of objects in the Oort cloud); much longer than that, and it will go away far enough to be captured by the gravitational field of other stars.

A short term interest rate occurs over a short period of time. A long term interest rate occurs over a long period of time.
the difference is that short-term goal is a goal that can be reach in a short period of time, but long term goals are goals that can plan to reach over an extended period of time.
because they are short term long term you what you say ,mister tell your teacher he/she is weird
It is a short but unspecified period of time.
the difference is that short-term goal is a goal that can be reach in a short period of time, but long term goals are goals that can plan to reach over an extended period of time.
yes, that's getting your period. it's as long or as short as it wants to be
