Comet Hyakutake won't be sighted again for a very long time.

Here's why:

* Long orbital period: Hyakutake has a very long orbital period, estimated to be around 70,000 years.

* Last appearance: It was last visible in 1996.

* Unpredictable trajectory: Even with a long period, comets can be influenced by gravity, making their exact return date uncertain.

So, unfortunately, we won't see Hyakutake again in our lifetimes, or likely for many generations to come.
