Can I Graduate in Astrophysics with Undergrad in Mech Eng?

[cheesefondue]

is it posible to graduate in astrophysics after undergrad in mechanical engineering, this is what I've currently planned and I'm already one semester into my engineering undergrad course. is it necessary that i switch or is it possible to study some of the fundamentals of astro on my own and then graduate after my engineering undergrad?
