A group of astronomers want to change the definition of a planet.
Why it matters: Their new proposed definition wouldn't bring Pluto back into the planetary fold, but it could reclassify thousands of celestial bodies across the universe.

Max Polyakov is co-founder of Firefly Aerospace, a Texas-based rocket maker valued last year at $1.8 billion.
Why it matters: He also was forced to dump his shares in the company, after investing around $200 million, by a U.S. government that now seems to be admitting a mistake.
