After Venus, Jupiter and the crescent moon wowed stargazers with a picturesque celestial triangle last week, the show is not over.

The trio will downsize to a duo this week as the two brightest planets, Venus and Jupiter, continue to converge.

Southern Astronomical Society President Noeleen Lowndes says Venus is the one moving towards Jupiter while Jupiter continues at a relative snail pace.

"Venus orbits faster than Jupiter because it is in closer proximity to Earth, whereas Jupiter takes 12 years to go around the sun," Ms Lowndes said.
