Scott Manley is one of the best known spaceflight video makers on youtube, with 1.8 million subscribers to his channel, and almost 700 million views over the last 15 years. Originally known for playing Kerbal Space Program and explaining the orbital mechanics, this transitioned into stories and explanations of real spaceflight and astrophysics.
Originally from Scotland he studied Astrophysics for a decade before moving the the US to work in online music, where he embraced his love of music and became a DJ hoping to turn his hobby into a second career. That didn’t happen, instead the Youtube channel took over.
Somewhere along the way Scott got a minor planet named after him – asteroid 1999 FU was renamed 33434 Scottmanley, it’s a small main belt asteroid at around 2.9AU and maybe 4.6km across.
