This week, the two brightest planets in our solar system, Venus and Jupiter, will meet in the western twilight sky, offering a spectacular sight for stargazers. The planets are currently positioned in the constellation Gemini and will be separated by about 1.5 degrees, roughly the width of three full moons. They will appear low above the western horizon after sunset, so a clear sightline and perhaps a hilltop vantage point will enhance the view.
How to Spot the Planets
Venus is the easier of the two to spot, shining brilliantly as the "evening star" at a magnitude of about -4.0. Jupiter, while fainter, remains bright at magnitude -1.9. Both planets are situated in Gemini, but the constellation's stars will only become visible as the sky darkens. The twin stars Castor and Pollux will be the first to appear.
For those with an excellent view of the western horizon, there is also a chance to spot Mercury, which lies midway down the bodies of the twins. However, it will be a race against time as the sky darkens before Mercury slips below the horizon.
Viewing Tips
The best time to observe is around 21:45 BST, looking west-northwest. No stars will be visible initially, but Venus and Jupiter will stand out brilliantly against the darkening sky. A pair of binoculars can enhance the view, but the planets are easily visible to the naked eye.
This conjunction is a rare treat, as such close alignments of Venus and Jupiter do not occur frequently. Make sure to catch this celestial event before the pair sets below the horizon.
