Asteroids are remnants of the formation of our solar system, and while many can be found within the asteroid belt between the orbits of Mars and Jupiter, some cannot. One such object is asteroid (162173) Ryugu, a 1 km-wide near-Earth asteroid believed to have originated in the asteroid belt. However, it has since moved to cross Earth's orbit, located 300 million km from our planet.

Snowball Earth defines periods of our planet's history when ice spanned the globe, even reaching the equator. The planetary-scale freeze is thought to have been driven by ice sheet expansion triggering a climatic tipping point that led to runaway ice-albedo feedbacks: the ice sheets reflected incoming solar radiation back to space, causing climate cooling and continued ice sheet formation.

Chondritic meteorites (chondrites) are some of the oldest rocks in our solar system, forming 4.5 billion years ago. Therefore, their primitive composition means that they offer a window into the origins of planet formation, particularly as their major elements (heavier than hydrogen and helium, including oxygen, silicon, magnesium, iron and nickel) closely reflect the sun's photosphere composition.
