Astrochemistry is the examine of the abundance and reactions of molecules within the Universe , and their interaction with radiation 97 The self-discipline is an overlap of astronomy and chemistry The phrase “astrochemistry” may be applied to both the Solar System and the interstellar medium The research of the abundance of elements and isotope ratios in Photo voltaic System objects, similar to meteorites , can be called cosmochemistry , whereas the examine of interstellar atoms and molecules and their interplay with radiation is typically called molecular astrophysics.
Our photo voltaic system consists of the sun, planets, dwarf planets (or plutoids), moons, an asteroid belt, comets, meteors, and other objects. But the variety of constellations and stars we’re able to see every year is actually a very small number out of the plethora of stars within the sky.
