Jupiter and Venus appeared to briefly meet in the sky overnight, in a rare planetary conjunction that some captured on camera.

The two planets are actually several hundred million kilometres (and a few planets) apart, but late Sunday and early Monday their orbits lined up in such a way that they appeared to the naked eye as two side-by-side pinpoints of light. The incident occurred in the early morning hours of Monday, with some in the U.K. glimpsing it as the sun rose.

The two planets appear close together approximately once every two years, but Monday they came much closer than usual, York University physics and astronomy professor Paul Delaney said.

“To get as close as this, that is a little rare,” Delaney told CTV News Channel. He said the two planets appeared as bright pinpoints approximately half the diameter of the moon apart in the night sky.

“Venus is incredibly bright. Jupiter is also quite bright, so having these two beacons so close together is a really pleasant sight,” he said.

Delaney said the occurrence, which happened at approximately 1 a.m. Eastern time, was even more enjoyable because the moon was close by and twilight was forming. “In a sense it was almost a triple-header,” he said.
