Where can I buy an Aurora coin?

Excuse me, could you please clarify where exactly I could go to purchase an Aurora coin? I've been hearing a lot about this cryptocurrency lately and I'm really interested in investing in it, but I'm not sure where to start. Is there a specific exchange or platform that I should be using? Additionally, are there any precautions or considerations that I should keep in mind before making a purchase? I'd really appreciate your guidance on this matter.
