THE next time the planet travels across the sun will be in 105 years.
"If you can see the mole on Cindy Crawford's face, you can see Venus," Van Webster, a member of the Los Angeles Astronomical Society, told anyone who stopped by his telescope for a peek on Mount Hollywood.
For astronomers, the transit was not just a rare planetary spectacle, but an event they hoped would spark curiosity about the universe and our place in it.
Sul Ah Chim, a researcher at the Korea Astronomy and Space Science Institute in South Korea, said he hoped people see life from a larger perspective, and "not get caught up in their small, everyday problems".
While astronomers used the latest technology to document the transit, American astronaut Don Pettit aboard the International Space Station was planning to take photos of the event and post them online.
In Los Angeles, throngs jammed Mount Hollywood where the Griffith Observatory rolled out the red carpet for Venus. The last time the city witnessed a Venus transit was in 1882.
Venus, which is extremely hot, is one of Earth's two neighbours and is so close in size to our planet that scientists at times call them near-twins. During the transit, it appears as a small dot.
This will be the seventh transit visible since German astronomer Johannes Kepler first predicted the phenomenon in the 17th century.
