The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

When Togepi and penises combine to create the tumblr ~f4m0us~ Togepenis who posts about cute guys/girls, Pokemon, and cats. Her trademark is her extreme use of sarcasm and witty retorts to people who ask her dumb questions. She is not to be taken seriously, and if you do you will be mocked mercilessly. It is unknown the exact number of followers she has as it is always growing, but it is definitely in the thousands, making her Tumblr famous.

The queen of Tumblr-
She is a complete bitch that no one can resist.
