Mars-Saturn, Jupiter-Venus Conjunctions Happening This Month!

Skywatchers, you have the opportunity to see not just one, but two planetary conjunctions during the month of April 2022!

A conjunction is a celestial event in which two planets, a planet and the Moon, or a planet and a star appear close together in Earth’s night sky. Conjunctions have no profound astronomical significance, but they are nice to view. In our Solar System, conjunctions occur frequently between planets because the planets orbit around the Sun in approximately the same plane –  the ecliptic plane – and thus trace similar paths across our sky.

The first planetary meet up occurs on the mornings of April 4 and 5 before sunrise and includes Mars and Saturn, with Saturn being the brightest. These two planets will come together, appearing as almost a single point of light. However, if you grab your binoculars, you’ll easily see the scene with the planets switching positions on each morning.

We will also see a bright Jupiter ascend quickly in the morning twilight, heading towards Venus in the final week of April. Catch a great view of the planets on the morning of April 27, which will include a waxing Moon.

Jupiter and Venus will then meet in conjunction during the morning of April 30 – appearing to nearly collide into each other. Due to the glare from both planets, observers will see them merge into one very bright, spectacular glow!

Venus’s orbit is closer to the Sun than the Earth’s, and Jupiter’s orbit is much farther away, so the proximity is an illusion, occurring only because Earth, Venus, and Jupiter happen to be approximately aligned. This celestial event will continue on the morning of May 1, but the positions of the planets, Jupiter and Venus, will be reversed.

Jupiter and Venus Conjunction

On Tuesday, June 30, there will be a conjunction of Jupiter and Venus. A conjunction is a celestial event in which two planets or a planet and the moon or a planet and a star appear close together in the night sky. Conjunctions have no real astronomical value, but they are nice to view. While conjunctions aren’t as rare as one might think, this conjunction of Jupiter and Venus will be more impressive than most.

The casual backyard observer may have noticed that these two planets have been moving closer together for the past few weeks. On June 30, they will be so close that one will be able to hold a finger up and cover both Jupiter and Venus at the same time. In reality, the planets are hundreds of millions of miles apart. On June 30, Venus is about 46 million miles from Earth, and Jupiter is 560 million miles from Earth. Looking up at the sky, Venus appears to be much brighter than Jupiter. That is only because Venus is so much closer to Earth. Jupiter, the largest planet in our solar system, is actually over 11 times bigger than Venus, but it is dimmer when looking at the sky because of its great distance from our planet.

Typically the best conditions for stargazing involve a dark sky, so getting away from urban areas will make stars and faint objects like nebulae and galaxies more visible. The Jupiter and Venus conjunction will be easily bright enough to see from any location, even large cities. The best hours for viewing will be during evening twilight and up until 10:30 PM local time, when the planets will set behind the western horizon.cooke
