Comets are primarily composed of ice, consisting of frozen gases such as water, carbon dioxide, and methane.

Asteroids are typically composed of rock and metal, with elements such as iron, nickel, and carbon being common. Hydrogen is not a major component of asteroids.

The European Space Agency's Rosetta mission successfully landed the Philae lander on comet 67P/Churyumov-Gerasimenko in 2014.

C-type asteroids are known for their high carbon content and are often associated with primitive materials in the solar system.

Ceres is the largest asteroid in the solar system, classified as a dwarf planet due to its spherical shape and gravitational dominance in its orbit.

Olivine is a common mineral found in asteroids, particularly in stony asteroids. It is a silicate mineral composed of iron and magnesium.

Comets are believed to have delivered a significant amount of water to Earth during their impacts, contributing to the formation of the oceans.

M-type asteroids are known for their high metal content, primarily composed of iron and nickel.

NASA's Deep Impact mission successfully impacted comet Tempel 1 in 2005, providing valuable insights into the comet's composition and structure.

Carbon dioxide is a common gas found in comets, along with other volatile compounds such as methane and ammonia.

The Main Asteroid Belt is the largest asteroid belt in the solar system, located between the orbits of Mars and Jupiter.

S-type asteroids are known for their high silica content, primarily composed of silicate minerals.

NASA's Deep Impact mission successfully impacted comet 9P/Tempel 1 in 2005, providing valuable insights into the comet's composition and structure.

Pyroxene is a common mineral found in comets, particularly in their rocky cores. It is a silicate mineral composed of calcium, magnesium, and iron.

The European Space Agency's Rosetta mission successfully landed the Philae lander on comet 67P/Churyumov-Gerasimenko in 2014.
