It's Space Day, but traveling the vast entity that is space would take far longer than a single day.

It's big out there! And, based on our current level of technology, here's about how long it would us take to reach:

The moon: 1-3 days

Mars: 150-300 days

The "end" of our solar system: 40 years

The nearest star: 80,000 years

The nearest galaxy: 749,000,000 (that's 749 million) years.

The end of the known universe: 225,000,000,000,000 years (that's 225 trillion) years.
