'Else Pizarro' apart from planets moons and stars the objects that are most commonly seen in our solar system are comets and asteroids.
The two types of objects are distinguished by their properties with comets being made up of ice and rock that release a tail of vapor.
Elsa Pizarro is the exception to the rule first recorded in 1979 it was designated as a minor planet with a stable orbit in between those of mars and Jupiter but the more it was studied the stranger it turned out to be it's not regarded as both an asteroid and a comet.
Since it behaves like an asteroid and is orbiting where other asteroids come from. But at the same time develops a tail during certain parts of its orbit this raises further questions because it could signify the presence of water in the asteroid belt which may provide clues as to where the water on earth came from in the first place.
The plan currently is to launch a probe in 2028 that will be able to land on Els Pizarro five years later and if it's able to collect the right samples it could even provide a deeper understanding for how our planet and perhaps life developed.
