Sir James Paul McCartney, MBE (born 18 June 1942) is an English singer-songwriter, multi-instrumentalist, and composer. With John Lennon, George Harrison, and Ringo Starr, he gained worldwide fame as the bassist of the rock band the Beatles, one of the most popular and influential groups in the history of pop music; his songwriting partnership with Lennon is one of the most celebrated of the 20th century. After the band's break-up, he pursued a solo career and formed Wings with his first wife, Linda, and Denny Laine.

McCartney has been recognised as one of the most successful composers and performers of all time, with 60 gold discs and sales of over 100 million albums and 100 million singles of his work with the Beatles and as a solo artist. More than 2,200 artists have covered his Beatles song "Yesterday", more than any other copyrighted song in history. Wings' 1977 release "Mull of Kintyre" is one of the all-time best-selling singles in the UK. A two-time inductee into the Rock and Roll Hall of Fame (as a member of the Beatles in 1988, and as a solo artist in 1999), and a 21-time Grammy Award winner (having won both individually and with the Beatles), McCartney has written, or co-written 32 songs that have reached number one on the Billboard Hot 100, and as of 2014 he has sold more than 15.5 million RIAA-certified units in the United States. McCartney, Lennon, Harrison and Starr received MBEs in 1965, and in 1997, McCartney was knighted for his services to music.

Venus

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°.

Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System, even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had oceans in the past, but these would have vaporised as the temperature rose due to a runaway greenhouse effect. The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind. Venus's surface is a dry desertscape interspersed with slab-like rocks and periodically resurfaced by volcanism.

Mars

Mars is the fourth planet from the Sun and the second smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.

The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.
