Space Terms to know about
Impact Crater :
An impact crater is a circular
depression in the surface of
a solid astronomical object formed
by the hypervelocity impact of a
smaller object.
Kuiper Belt :
The Kuiper belt is a circumstellar
disc in the outer Solar System,
extending from the orbit of Neptune
at 30 astronomical units to
approximately 50 AU from the Sun. It
is similar to the asteroid belt, but is
far larger—20 times as wide and
20–200 times as massive.
Oort Cloud:
The Oort cloud, sometimes called
the Öpik–Oort cloud, first described
in 1950 by the Dutch astronomer
Jan Oort, is a theoretical concept of
a cloud of predominantly icy plane-
tesimals proposed to surround the
Sun at distances ranging from
2,000 to 200,000 AU.
