Neptune, Mercury to Brightly Appear in Sky next Tuesday

Sky lovers will have a precious chance to observe rare clear appearances for two among the youngest planets in the Milky Way: Mercury, and Neptune, Next Tuesday, September 14.

Neptune will conquer the sky and shine as a small blue spot in the heart of the sky. This shining will be the brightest for Neptun as it will be at its closest point to the Sun, and the whole face of the planet could catch the biggest amount of Sun rays in its annual orbit duration.

Regarding Mercury, the planet's elongation will reach its climax on the same day, so it will appear somehow clearer and bigger.

The best time to catch Mercury will be the earliest minutes after the sunset as it will stand at its highest point above the horizons from the west.

Skywatchers can observe Mercury with the naked eye, however, Neptune will be only detected by small and medium-sized telescopes.
