Josep Comas i Solà (1868 – 1937) was a Spanish astronomer. He wrote his first astronomy notes at the age of ten, and was only fifteen when he published an article in a French specialist magazine.
The asteroids 1102 Pepita (from his nickname Pepito) and 1655 Comas Solà are named after him, as is Comas Sola crater on Mars. He discovered 11 asteroids during 1915–1930. He also discovered the periodic comet 32P/Comas Solà ( image link under ) and co-discovered the non-periodic comet C/1925 F1.
