Who was the first astronomer to see the phases of Venus?
Galileo Galilei was the first astronomer to see the phases of Venus in 1610, providing evidence for the heliocentric model of the solar system proposed by Copernicus.
Venus is a planet, and like all planets, it will not "die." However, its surface conditions will continue to change over billions of years due to various geological processes and interactions with the sun.
Has anyone set foot on Venus's?
No. The moon is the only place man has been when leaving earth. Mars is arguably a "more interesting" target for explanation. Venus is shrouded in clouds, and the surface is extremely hot and hostile. Survival there would be problematic if we decided to go there. Current technology would only allow sirvival there for a short time. Those clouds? They're sulfuric acid. Nasty stuff. A link can be found below so you can read about the surface conditions on Venus.
The temperature of Venus is fairly constant:-
How could the craters on venus be described?
The craters on Venus vary in size and shape, with some being large and circular while others are more irregular. Due to the planet's thick atmosphere, many craters appear eroded or partially filled in by volcanic activity. Overall, Venus's craters can provide important insights into the history of impacts and geological processes on the planet.
What two factors cause the high temperatures on venus?
The high temperatures on Venus are primarily caused by its thick atmosphere, composed mainly of carbon dioxide, which creates a greenhouse effect by trapping heat from the sun. Additionally, the intense surface pressure on Venus contributes to the retention of heat.
Is Venus smaller or larger than Neptune?
Venus is far smaller than Saturn. Venus is the thrid smallest planet in the solar system, larger than Mars and Mercury, bust smaller than everything else. Saturn is the second largest planet. Only Jupiter is larger.
What kind of atomosheric gases does Venus have?
Major components (by volume)
96.5% carbon dioxide (CO2)
3.5% nitrogen (N2)
Minor components (parts per million)
150 sulfur dioxide (SO2)
70 argon (Ar)
20 water vapor (H2O)
17 carbon monoxide (CO)
12 helium (He)
7 neon (Ne)
Who was called the Morning Star of Independence?
Simón Bolívar, a leader in the South American wars of independence, was often referred to as the "Morning Star of Independence" for his role in liberating several countries in Latin America from Spanish colonial rule in the early 19th century.
How does Venus size and atmosphere compare to earth?
Venus is similar in size to Earth, with a diameter approximately 95% that of Earth. However, Venus has a much denser atmosphere compared to Earth, mostly composed of carbon dioxide with thick clouds of sulfuric acid. These atmospheric conditions create a runaway greenhouse effect, leading to extreme surface temperatures and pressure on Venus.
Venus is volcanic, although it seems that the activity greatly subsided several hundred million years ago. There are several "continents" arising from the smooth volcanic plains, one of which is about the size of South America, with another one about the size of Australia. There are nearly 1000 impact craters, with about 85% of them in pristine condition, giving credence to the theory that volcanism has subsided.
What direction does Venus spin on its axis?
Venus rotates clockwise, when viewed from above the Earth's North Pole.
How big is mercury compared to Venus?
Mercury's diameter is 4,880 km, while Venus is much bigger, having a diameter of 12,104 km. so this means that you could fit 2 of them into the diameter of Venus, with enough room left to put 41% of another one on it.
What are some discoveries about Venus?
It is hypothesized that Venus was cooler and more hospitable at some point in its life, but currently, surface temperatures, pressures, and chemicals destroy probes or render them mostly blind in minutes. Its very difficult to explore.
Does Venus have a very tilted axis giving it very extreme seasons?
No it does not because its axial tilt is only 3%.I was just learning this in science or otherwise I woud not have known about this. So no Ceres does not have seasons!
During superior conjunction how far is Venus from Earth?
During superior conjunction, Venus is on the opposite side of the Sun from Earth, typically located around 1.7 astronomical units (AU) away from us. This distance can vary due to the elliptical orbits of both Venus and Earth.
What is Venus' gravity compared to earth?
The gravity on the surface of Venus is 0.904 of that on the surface of Earth.
You may find the related link below useful.
No, Venus is not a burned out sun (star). It isn't large enough - considering its composition - to be the "remains" of a stellar body. (Yes, a neutron star is small compared to Venus, but it is composed of neutrons. Venus isn't.) Stars need a minimum mass to begin a fuision cycle, and (if they don't go supernova) they leave behind a minimum mass when they die. This mass may vary is size and composition, but Venus does not conform to any of the "corpses" of any known type of star. There are a number of other reasons a star could not have existed in the orbit of Venus, and they have to do with the evolution of the inner planets.
How did the planet Venus get so hot?
Venus got so hot because of all the gases in its atmosphere that they started a greenhouse effect on it making it now the hottest planet in the solar system.
The temperature of Venus's core is estimated to be around 5000 degrees Celsius (9,032 degrees Fahrenheit). This high temperature is due to the heat generated during the planet's formation and the decay of radioactive elements in its interior. These extreme conditions contribute to Venus's hot surface temperatures and hostile environment.
Where did planet Pluto get its name?
Eris is named after the goddess Eris, a personification of strife and discord.
Is Venus's the same size as earth?
In size and mass, it is similar to the Earth, and is often described as Earth's "sister" or "twin".The diameter of Venus is 12,092 km (only 650 km less than the Earth's) and its mass is 81.5% of the Earth's. Conditions on the Venusian surface differ radically from those on Earth, owing to its dense carbon dioxide atmosphere. The mass of the atmosphere of Venus is 96.5% carbon dioxide, with most of the remaining 3.5% being nitrogen.
So even though they are alike in size and mass, it is not liveable, for now atleast.
Compositionof the atmosphere in Venus'?
Venus's atmosphere consists of Carbon Dioxide (96.5%), Nitrogen (3.5%), Sulfur Dioxide (150 parts per million), Argon (70 ppm), Water Vapour (20 ppm), Carbon Monoxide (17 ppm), Helium (12 ppm), Neon (7 ppm), Hydrogen Chloride (0.1-0.6 ppm), and Hydrogen fluoride (0.001-0.005 ppm).
