As a three year old with a passion for stars he went on a tour of the Holcomb Observatory and Planetarium at Butler University in Indianapolis.

This is the day his mother Kristin Barnett would never forget (via the IndyStar):

“We were in the crowd, just sitting, listening to this guy ask the crowd if anyone knew why the moons going around Mars were potato-shaped and not round.

Jacob raised his hand and said, ‘Excuse me, but what are the sizes of the moons around Mars?’ ”

The lecturer answered, and Jacob looked at him and said the “gravity of the planet . . . is so large that (the moon’s) gravity would not be able to pull it into a round shape.”

Silence.

Meet Jacob Barnett, now 12 years old, mildly autistic and with an IQ of 170 – higher than Stephen Hawkings and Albert Einstein. At age three, he was solving 5,000 piece jigsaw puzzles and now he’s already got a paid research position at Indiana University.

For a taster of this little man’s out-of-this-world genius, watch this (and enjoy his mother’s comedic timing). There are plenty more videos on his mother’s YouTube channel too.
