Asteroids are large rocks in outer space that are not round due to weak gravity. They are categorized based on how they reflect sunlight. Some asteroids exist between Mars and Earth, and asteroid impacts on Earth have increased since the 1840s. Mars is the only planet believed to potentially support life, though past attempts to launch comets to its surface have all failed, with one nearly landing on an asteroid instead.

1. Asteroids
An asteroid is a large rock in outer
sand. Due to their smaller size,
asteroids do not have enough gravity
to pull themselves into the shape of a
ball. Astronomers group asteroids
into different categories based on the
way they reflect sunlight.
Between Mars and the Earth the are
some asteroids. The impact of
asteroids hitting the Earth has gone
higher since the 1840s.

2. Mars
Planet Mars is
believed to be the
only which they
expect to find if the
is anyone on it. in
the past years
scientist have tried
launching comets
on Mars but they
all failed. the
closest comet to
