The many kinds of moons

The Many Moons of Jupiter Galileo published his discovery of the first 4 moons in 1610. That number stayed stubbornly at 4 until 1892 when a 5th was discovered by Edward Emerson Barnard, known better for Barnard’s Star. Since the 1900’s many more have been discovered as telescopes improved. The minor moons, as the 88 non-Galilean ones are known, are generally much smaller, having radii of only a few kilometers.

The first of four supermoons expected this year, also known as the Buck moon, dazzled observers around the world on Monday, lighting up the skies above above Río de la Plata as well as Egypt’s Great Pyramids in Giza. #supermoon #moon #argentina #egypt #channel4news #c4news | Channel 4 News
