How do comets begin their orbits? What could have happened to
Halley's Comet between 1832 and 1911? It seems that Halley's comet slowed
down for that period of time-the time of reoccurrence between 1832 and 1911.
The current pattern of reoccurrence seems to be once every 74 years, then 76
years, then 74 years, then 76 years and so on. The time between 1832 and 1911
displays a 79 year reoccurrence. Please help us in answering these questions.
Comets spend most of their time in the Oort cloud, well beyond
the orbit of Pluto. Everything that is part of our solar system is in orbit.
The orbits of comets are unpredictable because of gravitational interactions
with the gas giant planets, especially Jupiter.
