Planetary geologist Kirby Runyon is lead author of an abstract that proposes a new, geophysical definition of what a planet is. It would grant our solar system 110 planets, including Pluto and the moon. Up, up and away with Digital Editor Jason Davis on World View’s balloon ride to just below the edge of space. It’s the asteroid of love and it’s the destination of this week’s space trivia contest. Bill Nye has the week off.

High-resolution enhanced-color global MVIC portrait of Pluto
This beautiful high-resolution image of Pluto is from a single observation with the MVIC imager on the Ralph instrument. It is an enhanced-color view made of three images captured through infrared, red, and blue filters. The three individual images were denoised, deconvolved, and enlarged by a factor of 2 before being combined into this stunning portrait.
