What's Happening?
Mercury will reach its greatest western elongation on August 19, providing an opportunity for stargazers to observe the planet at its farthest point from the sun in the morning sky. This astronomical event occurs when Mercury is at its maximum angular distance from the sun, making it visible to the naked eye. Observers in locations such as New York can expect Mercury to rise about 16 degrees above the eastern horizon before the sun appears. The planet will be visible in the constellation Cancer, accompanied by Venus and Jupiter, and a waning crescent moon. Stargazers are advised to look east in the hour before dawn for the best chance to spot Mercury.
