 Interesting Questions, Facts, and Information
 Venus
| The first method to see through the dense clouds covering Venus (in the 1950's) was what? | Venus
|
radio astronomy from earth.
| The surface pressure on Venus is equivalent to what? | Venus
|
| Venus is so hot due to what? | Venus
|
all of the other answers are correct (volcanic activity, thick atmosphere, proximity to the sun).
| On Earth, clouds are composed of water vapor. What do the clouds on Venus consist of? | Venus
|
| What is odd about the way Venus spins? | Venus
|
it spins backwards. Venus spins backwards relative to the other planets.
| Which recent space probe accomplished the most detailed observations of Venus yet? | Venus
|
| What is the rotation period (day) of Venus in Earth days? | Venus
|
| What is the surface gravity of Venus relative to earth? | Venus
|
| What is the average surface temperature of Venus? | Venus
|
7,600 miles. Venus is sometimes refered to as Earth's twin do to its size being similar.
Aphrodite. Aphrodite is the greek goddess of love. Cassiopeia is a constellation (the Queen), Andromeda is a constellation (the Chained Maiden) and Athena is a Greek goddess.
48 degrees. At its maximum elongation, Venus can be easily viewed in total darkness (after twilight ends).
t. You must know exactly where to look, and of course, you need clear skies.
None. Like Mercury, Venus has no natural satellites.
Carbon dioxide. Venus' atmosphere is 96 percent carbon dioxide. The remaining major components are 3% nitrogen and 0.003% water vapor.
sixth. From largest to smallest; Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury.
.81 times that of Earth. Besides the mass and size of Venus being similar to Earth, it has little in common with the Earth.
177.3 degrees. More than any other planet!
Phosphorus and Hesperus. Phosphorus meaning morning star and Hesperus meaning evening star. Zeus and Apollo are gods, According to the Roman legend, Romulus was the founder of Rome and Remus was his twin brother. Laurel and Hardy were a comedian act.
5.2 that of water. Earth's density is 5.5 that of water, making Earth slightly more dense than Venus. Mercury fits in between Venus and Earth at 5.4 times the density of water.
None. Although Jupiter's magnitude can reach -2.5, it can't match Venus' magnitude of -4. Only the Sun and the Moon are brighter than Venus, but they are not planets!
| Venus has been visited by human spacecraft more than 20 times. What spacecraft was the first to touch the surface of Venus? | Our Sister Planet Venus
|
Venera 3. It's often written that Venera 9 in 1975 was the first spacecraft to land on the surface of another planet. This is not correct. In 1966 Venera 3 crash-landed on Venus. Venera 7 had a landing capsule which was the first object to return data from Venus's surface. Mariner 2 was the first object to "visit" Venus with a fly-by in 1962.
| Since Venus orbits Sol within Earth orbit, Venus from time to time can (from Earth) be seen passing in front of Sol. This is called transit. These transits are important astronomical events. The first evidence of Venus's atmosphere was found because of a transit. When was this? | Our Sister Planet Venus
|
1761. The discovery was made by the Russian astronomer Mikhailo Vasilevich Lomonosov (1711-1765). Mikhailo was also a well-known writer and chemist and is often credited with being a founder of Russian science.
| Venus is the brightest object in the sky after Sol and Moon. Therefore it's been known since prehistoric times. For a long time it was thought to be two different objects. What did the Greeks originally call them? | Our Sister Planet Venus
|
Eosphorus and Hesperus. Aphrodite is (as written above) the Greek counterpart to Venus. Hephaestus is her husband (the smith god). Kypris and Cytherea are two alternative names for Aphrodite. Hymenaios and Aeneas are two of Aphrodite's sons.
Eosphoros and Hesperus are simply the morning and evening stars. They are the sons of Eos (goddess of dawn) and Astreaus (father of stars).
Venus always faces Sol the same way.. It is not yet known why Venus always shows us the same face when we are closest together.
Ishtar Crater. Aphrodite Terra is one of two large highland areas (the other is Ishtar Terra), it's placed along the equator. Maxwell Montes is the highest mountain on Venus and is placed on Ishtar Terra on the northern hemisphere. Guinever Planitia is a broad depression west of Ishtar Terra. Ishtar Crater is nothing.
| The atmosphere of Venus is very thick. The pressure on the surface is ~90 atmospheres. The inner layers (0-40 km.) consist mainly of carbon dioxide. The outer layers (40-60 km.) are clouds of sulphuric acid drops. Do these drops rain down onto the surface? | Our Sister Planet Venus
|
No. The rain only reaches down to about 20 km. above the surface; here it evaporates due to the high surface temperature.
| Venus's alchemical symbol is also the female symbol. This symbol also symbolizes a day (Friday) and a metal, which? | Our Sister Planet Venus
|
Copper. Astrologers would say that it's the circle of life above the cross of spirit. Others would say it's the circle of unity above the cross of Earth.
| Venus is the Roman goddess of love. Her Greek counterpart is Aphrodite, but what is the Babylonian counterpart? | Our Sister Planet Venus
|
Ishtar. Anu is her father and Ereshkigal (goddess of the underworld) her sister. Tammuz was her lover but also her brother.
| How did Venus help assert that the Earth was not the center of the Solar System? | Venus, the Gold Star
|
It shows phases like the Moon. Much like the Moon, Venus can be seen telescopically in the shape of a crescent, a half circle, or anywhere in between. Galileo had noticed this in the early 1600's.
They can both cast a shadow on Earth. Though hardly noticable, Venus's shadow can be seen on Earth during its transit of the Sun. One would need to use filter paper to see it.
