 The
solid part of the comet, its "nucleus," is like a dirty,
hard-packed snowball with pockets of air trapped inside.
When a comet's orbit brings it into the inner solar system,
where you and I live, some of the ice and gas are heated by
the Sun, and they expand to form a cloud around the nucleus.
Although the nucleus may be only a few kilometers across,
the cloud, called a coma, can be thousands of kilometers
across -- even larger than Earth. The coma blocks our view
of the nucleus, just as a cloud blocks your view of an
airplane flying inside it. |
