So no matter how big or how small a planet or an asteroid is if its orbiting a planet it is called a moon, but our moon is pretty spherical and unique and when we look at Mars's moons Phobos and Deimos they are pretty underwhelming, I mean one is the size of manhattan and they both look like potatoes, so its pretty dissapointing to call them moons. • Speaker: Neil deGrasse Tyson • #space #cosmos #neildegrassetyson #space #universe #shorts #short
