The History Of Venus Before we get into the facts and figures and the numbers behind the planet that is Venus, we probably should talk about how we discovered it. After all, Astronomy has been going on for a very long time, and people have found planets like Venus like before you would expect them to. In the Old Babylonian period, the planet Venus was known as Ninsi'anna, and later as Dilbat. The name "Ninsi'anna" translates to "divine lady, illumination of heaven", which refers to Venus as the brightest visible "star". The ancient Greeks initially believed Venus to be two separate stars: Phosphorus, the morning star, and Hesperus, the evening star. Pliny the Elder credited the realization that they were a single object to Pythagoras in the sixth century BCE, while Diogenes Laërtius argued that Parmenides was probably responsible for this rediscovery. Though they recognized Venus as a single object, the ancient Romans continued to designate the morning aspect of Venus as Lucifer, literally "Light-Bringer", and the evening aspect as Vesper, both of which are literal translations of their traditional Greek names. When the Italian physicist Galileo Galilei first observed the planet in the early 17th century, he found it showed phases like the Moon, varying from crescent to gibbous to full and vice versa. When Venus is furthest from the Sun in the sky, it shows a half-lit phase, and when it is closest to the Sun in the sky, it shows as a crescent or full phase. This could be possible only if Venus orbited the Sun, and this was among the first observations to clearly contradict the Ptolemaic geocentric model that the Solar System was concentric and centered on Earth. Which was one of many theories about how about our world and our universe were at the 'center of it all" when it fact that couldn't be further from the truth. The atmosphere of Venus was discovered in 1761 by Russian polymath Mikhail Lomonosov. Venus's atmosphere was observed in 1790 by German astronomer Johann Schröter. Schröter found when the planet was a thin crescent, the cusps extended through more than 180°. He correctly surmised this was due to scattering of sunlight in a dense atmosphere. Later, American astronomer Chester Smith Lyman observed a complete ring around the dark side of the planet when it was at inferior conjunction, providing further evidence for an atmosphere. Believe it or not, it wasn't until the 1900's when more details and research was done on Venus, mainly because its shape, distance and phases didn't give a lot of clues as to its various inner workings. Radar observations in the 1970s revealed details of the Venusian surface for the first time, thus giving scientists much more to work with. The first robotic space probe mission to Venus, and the first to any planet, began with the Soviet Venera program in 1961. The United States' exploration of Venus had its first success with the Mariner 2 mission on 14 December 1962, becoming the world's first successful interplanetary mission, passing 34,833 km (21,644 mi) above the surface of Venus, and gathering data on the planet's atmosphere. Since then, numerous probes and satellites have been taken to Venus to study it in some capacity. There has even been talks of putting a rover on the planet in the same style that NASA has done with Mars, but that hasn't happened as of yet. 7. Orbits and Rotations Venus is known as our "sister planet", because in many ways it's like Earth. It's only a little bit smaller, has an atmosphere that is full of gasses, and we do know that it has a definitive surface like certain other planets in our solar system, but we'll get to that more later. Although it should be noted that despite the similarities to Earth, there are just as many differences that we'll be covering a lot in this list for various reasons. If you want to get really trippy on how different Earth and Venus are, you need to talk about how Venus handles its days and years. Because not unlike its own neighbor, Mercury, Venus has a VERY slow rotation, but to the extent that it's actually longer than a year! Yeah, that's right, a day is longer than a year on Venus. Its orbital period, or how long it takes to make a full rotation around the sun, is about 225 Earth days, whereas a singular day on Venus is 243 days. That's weird. #InsaneCuriosity #Venus #TheSolarSystem
