The Big Bang Theory guest stars over the years have ranged from TV legends like George Takei to real-life scientists including Neil deGrasse Tyson. Do you remember all of the amazing guest stars? Join us in taking a look at some of The Big Bang Theory's best guest stars over the years!

The Big Bang Theory Guest Stars

One of The Big Bang Theory's best guest stars would come in season four's fourth episode, "The Hot Troll Division." Appearing in a fantasy of "Howard's", Star Trek legend George Takei attempts to give "Howard" and "Bernadette's" relationship advice.

Battlestar Galactica star Katee Sackhoff also appears alongside George Takei in "Howard's" fantasy world. Katee questions both men, suggesting "Howard" may have "latent homosexual tendencies" and questioning George's place to offer advice.

Astrophysicist Neil deGrasse Tyson has guest-starred in not just one but two episodes of The Big Bang Theory. Well-known because of his involvement with the demotion of Pluto as a planet, when "Raj" introduces Tyson to "Sheldon" in season four, "Sheldon" is not a fan. 

In Neil deGrasse Tyson's second guest appearance in The Big Bang Theory's twelfth season, we also get science comedian Bill Nye! Following a Twitter war instigated by "Raj", Tyson's next target is Bill Nye, whom he calls at the episode's end stating "we need to talk".
