Someone's been skipping their astronomy lectures. The image shows an orange (labeled "Sun") next to some smaller fruits/objects (planets), with Pluto being practically microscopic.
Size isn't the determining factor for planethood—otherwise my department head's ego would qualify as a celestial body. Stars are massive balls of plasma undergoing nuclear fusion, while planets are just rocky/gaseous objects orbiting stars.
By this logic, I should ask why my coffee mug isn't classified as a teacup despite being larger than my colleague's teacup. The astronomy department would have a collective aneurysm reading this.
