the orbits of Mercury, Venus, Earth and Mars are seen in motion from the top down against a spiderweb graph. Earth's orbit leaves a blue trail, while Venus's orbit leaves a yellow trail — Venus orbits the Sun at an average distance of about 108 million kilometres (about 0.7 AU) and completes an orbit every 224.7 days. Venus is the second planet from the Sun and orbits the Sun approximately 1.6 times (yellow trail) in Earth's 365 days (blue trail)

A photograph of the night sky taken from the seashore. A glimmer of sunlight is on the horizon. There are many stars visible. Venus is at the centre, much brighter than any of the stars, and its light can be seen reflected in the ocean. — Venus is always brighter than all other planets or stars as seen from Earth. The second brightest object on the image is Jupiter.

Venus is shown in various positions in its orbit round the Sun, with each position marking a different amount of surface illumination — Galileo's discovery that Venus showed phases (although remaining near the Sun in Earth's sky) proved that it orbits the Sun and not Earth

Lek mating arena, in which each male guards a territory of a few meters in size on average, and in which the dominant males may each attract up to eight females.^[117] In addition, each individual is shown with variations in personal space (bubbles), whereby higher-ranking individuals have larger personal space bubbles.^[118] Common bird leks typically have 25–30 individuals. A strict hierarchy accords the most desirable top-ranking males the most prestigious central territory, with ungraded and lesser aspirants ranged outside. Females come to these arenas to choose mates when the males' hierarchy has become established, and preferentially mate with the dominants in the centre.

Retrieved 29 May 2012. {{cite web}}: Check |url= value (help) "the venerable line about scientists having proved that a bumblebee can't fly appears regularly in magazine and newspaper stories. It's also the kind of item that can come up in a cocktail party conversation when the subject turns to science or technology. [...] Often, the statement is made in a distinctly disparaging tone aimed at putting down those know-it-all scientists and engineers who are so smart yet can't manage to understand something that's apparent to everyone else. [...] the story has had remarkable staying power, and the myth persists that science says a bumblebee can't fly. Indeed, this myth has taken on a new life of its own as a piece of "urban folklore" on the Internet."
