Oort Cloud and Scale of the Solar System (Infographic)

Informally, the term "solar system" is often used to mean the space out to the last planet. Scientific consensus, however, says the solar system goes out to the Oort Cloud, the source of the comets that swing by our sun on

How many light years in diameter is the solar system?

Astronomers suggest that the solar system is about 0.5 light year long or possibly even a full light year. The debate is not settled due to the Oort Cloud ( it is an entire cloud made up asteroids closing the solar system) and astronomers say that the Oort Cloud could be 1 light year in length. As it is part of the solar system, some astronomers already consider the solar
