About the paper Full textAbstract
Predicting asteroid and comet collisions with the Moon has similar problems as the collisions with the Earth. Universal time of the event, the longitude and the latitude of a point of possible falling and the parameters of the velocity vector in the point of falling can be determined for each case of the collision. If the nominal orbit of the body goes past the Moon, but the probability of the collision is still rather high, then a particular strip-shaped risk area (“a strip of the risk”) on the Moon surface is calculated for observations. The points of possible falling (which form the strip of the risk) are looked for by building variations of the body’s mean motion and finding those values which lead to collisions with the Moon. We have constructed an example of a heliocentric orbit with an uncertain mean motion within a particular range which leads to collisions with the Moon along some strip of the risk.

AB - Predicting asteroid and comet collisions with the Moon has similar
problems as the collisions with the Earth. Universal time of the
event, the longitude and the latitude of a point of possible falling
and the parameters of the velocity vector in the point of falling can
be determined for each case of the collision. If the nominal orbit of
the body goes past the Moon, but the probability of the collision is
still rather high, then a particular strip-shaped risk area (“a strip
of the risk”) on the Moon surface is calculated for observations. The
points of possible falling (which form the strip of the risk) are
looked for by building variations of the body’s mean motion and
finding those values which lead to collisions with the Moon. We have
constructed an example of a heliocentric orbit with an uncertain mean
motion within a particular range which leads to collisions with the
Moon along some strip of the risk.
