KEY POINTS

  • Venus' inferior conjunction will take place in June
  • The planet will pass between Earth and the Sun
  • Venus' shape is starting to change due to the conjunction

The planet Venus will pass in between the Sun and the Earth during a cosmic event known as the inferior conjunction. According to astronomers, the shape of Venus is expected to change in the days leading up to the event.

Venus is regarded as the third brightest object in the sky after the Sun and the Moon. It is also referred to as an evening star due to its prominent brightness after sunset.

In the next couple of days, astronomers noted that the shape of Venus, when viewed from Earth, would dramatically change as it moves in front of the Sun. The planet might even reach a point that it completely disappears in the sky.

Based on the observations by astronomers, Venus is becoming more slender. Specifically, its crescent shape became longer and thinner within the last couple of days.

“Even seven days has made a huge difference,” astronomer Radu Anghel from Bacau, Romania said, according to SpaceWeather.com. “Venus' changing shape is easy to spot even with a pair of binoculars.”

As explained by the website, the change in Venus’ shape is being triggered by its movement. As it moves closer to the Sun, it turns its dark side towards Earth. Because of this, only a narrow sliver of the planet’s dayside becomes visible from Earth. This causes Venus to look like a small version of a crescent Moon.

Venus’ movement is part of a cosmic event known as inferior conjunction, which is expected to fully take place on June 3. During this time, the planet will directly pass between the Sun and the Earth.

Astronomers believe that once this occurs, Venus’ silhouette will become so narrow that the tips of its crescent shape might touch.

Before it passes in between the Earth and the Sun, Venus will first have its own conjunction with Mars starting on Thursday (May 21), which will extend until Friday (May 22). Those looking to catch Venus’ conjunctions may do so by looking towards the western portion of the sky after sunset. It would be best to view the planet using a telescope or a pair of binoculars.
