Every now and then a scientific paper makes a real splash. We had one recently, to judge from recent headlines. “Moon rises to claim its place as a planet” said The Sunday Times on February 19, while the Mail Online asked “Is this lunarcy?”. The articles were among many responding to the humble paper: “A Geophysical Planet Definition”, which suggested that the criteria for determining what constitutes a planet need an overhaul. It argued that the moon, Pluto and several other bodies in the solar system should be upgraded to planets.
For decades, scientists have been of the belief that the Moon, Earth’s only natural satellite, was four and a half billion years old. According to this theory, the Moon was created from a fiery cataclysm produced by a collision between the Earth with a Mars-sized object (named Theia) roughly 100 million years after the formation of primordial Earth.
A beautiful full moon will grace our skies on Monday November 14 this year. Full moons always rise around sunset, so look for it towards the east during evening twilight. Every month, occasionally even twice a month, the full moon adorns the night. What makes this one so special is all the hype of the supermoon.
