We’ve reached the peak of the current Mars observing season today with the planet closest to Earth:62-million km or 38.5-million miles. At -2.5 magnitude and 22.6″ in diameter, Mars is a conspicuous, intense orange target in the sky that is brighter than any star, except our Sun and is only outshone by Venus and the Moon in the nighttime sky. When it reaches opposition next week, on October 13th, it will still be 22.4″ in diameter and a tad brighter at -2.6 magnitude. It will remain greater than 20″ in diameter for the whole month. So, weather permitting, put an eyepiece in the scope this month and show it to all your friends!
