20 Fun Facts about Asteroids and Comets by Arielle ChigerMost asteroids come from a belt that orbits the sun between the orbits of Mars and Jupiter. Comets are born in the frozen reaches beyond Neptune. Both are remnants leftover from the birth of our solar system billions of years ago. Readers will be amazed to learn all about these fascinating space rocks. The scientific text is paired with stunning photographs and illustrations of cosmic forces at work. A detailed graphic organizer provides a convenient study guide for comparing and contrasting comets and asteroids.
Asteroids and Comets: Facts
If the sun was as tall as a typical front door, Earth would be the size of a nickel, the moon would be about as big as a green pea and Ceres the largest object in the main asteroid belt would be as small as a sesame seed. The first discovery of an asteroid-moon system was asteroid Ida and its moon Dactyl in One asteroid, named Chariklo, is known to have two dense and narrow rings. More than 10 spacecraft have explored asteroids, and we have even landed on an asteroid NEAR Shoemaker landed on an Eros. Ceres, is both the first and largest asteroid to be discovered in by Giuseppe Piazzi ; it is the closest dwarf planet to the sun and it encompasses over one-third of the estimated total mass of all the asteroids in the asteroid belt. Due to solar wind, comets tails point away from the Sun, regardless of the direction in which the comet is traveling. If the sun were as tall as a typical front door, Earth would be the size of a nickel, dwarf planet Pluto would be the size of a head of a pin and the largest Kuiper Belt comet about km across, which is about one twentieth the size of Pluto would only be about the size of a grain of dust.
1.) If all of the asteroids were combined into a ball, they would still be much smaller than Earth's moon. If the sun was as tall as a typical front.

Amanda is a retired educator with many years of experience teaching children of all ages and abilities in a wide range of contexts. A comet is an icy object which orbits the sun. - A comet is a very small solar system body made mostly of ices mixed with smaller amounts of dust and rock.
Our solar system is filled with all sorts of interesting objects. Scientists are continuously studying these objects. Asteroids and comets are two kinds of bodies that orbit our sun and that scientists are still learning more about. Recent scientific studies have put asteroids and comets in the news. Let's take a closer look. Asteroids are rocky structures without atmospheres, and as far as we know, also without life.
