On July 14, NASA’s New Horizons probe will fly right by Pluto.
We've never visited Pluto before, so it's a pretty significant occasion.
New Horizons has been on its one-way trip to Pluto (and beyond) since it launched in 2006.
So people are getting pretty excited for it to finally arrive.
Some are even dressing for the occasion.
And, of course, the spacecraft has its own parody Twitter account.
The encounter will be fleeting, but we'll get a ton of data and new, close-up pictures.
In fact, we've already been learning a lot about Pluto and its moons in the run-up to closest approach.
After it leaves Pluto, New Horizons will fly off to study an object in the Kuiper belt, a billion kilometers past Pluto.
So mark your calendar and set an alarm.
(Or stay up.)
