What makes it difficulty to observe Venus from far away and to observe it from the within the planet?
Truth to be told, Venus is a notoriously difficult planet to observe because of its high luminosity. Due to its proximity to our star, combined with the planet's thick and highly reflective atmosphere, Venus reflects a lot of light from the sun.
What was the main technique used to study the solid surface of Venus?
What was the main technique used to study the solid surface of Venus? Radar images.
What reasons forced GK Gilbert to conclude that Meteor Crater had not formed as the result of meteor impact?
What reasons forced G. K. Gilbert to conclude that Meteor Crater had not formed as the result of meteor impact? There were no unusual patterns in magnetism around the crater, the ejected material from the crater had no additional mass added to it.
What is a popular theory for the difference in atmospheres of the Jovian planets versus the terrestrial planets?
What is a popular theory for the difference in atmospheres of the Jovian planets versus terrestrial planets? High temperatures and solar wind in the inner planets allowed most of the volatiles to be driven off the terrestrial planets, but not the Jovian planets.
Why is it difficult to see the surface of Venus through a telescope?
Venus is covered with clouds which are highly reflective. To the naked eye, in binoculars, and in a telescope it appears as a bright ball. It shines brighter than any star in the sky. However, because of these clouds, you won't be able to see the venus's surface.
How can we observe the surface of Venus?
Observing Venus Such appearances require no optics to enjoy and are wonderful events to share with non-stargazers to get them interested in amateur astronomy. In many cases, binoculars can enhance the view if Venus gets within a few degrees of the Moon or another planet. The crescent Moon, Venus, and much fainter Mars.
Why is studying Venus hard?
Exploring the surface of Venus is difficult because of the intense heat and crushing air pressure. The longest any spacecraft has survived on the surface is a little over two hours – a record set by the Soviet Union's Venera 13 probe in 1981. The probe returned the first color images of the surface of Venus.
Why can’t astronomers study the surface of Venus with visible light telescopes?
Why can't astronomers study the surface of Venus with visible light telescopes? Venus' thick atmosphere prevents us from seeing the surface.
Why do lunar scientists think the surface of the Moon was once a magma ocean?
Why do lunar scientists think the surface of the moon was once a magma ocean? The lunar highlands contain large amounts of the rock anorthosite, which is the light material that "floated" on the top of the magma ocean.
What is the principal gas in the Venusian atmosphere and is also a minor component of the atmospheres of Earth and Mars?
The atmosphere of Venus is made up almost completely of carbon dioxide. It also includes small doses of nitrogen and clouds of sulfuric acid.
Why does Jovian planets have greater number of natural satellite compared to terrestrial planets *?
For a short answer: The giant planets have more moons than the terrestrial planets because of their great masses which result in stronger gravitational fields. And giant planets also occupy greater space and hold larger volumes of mass in their surrounding atmospheres.
Which of the following is not a major difference between the terrestrial and jovian planets in our solar system?
Which of the following is NOT a major difference between the terrestrial and jovian planets in our solar system? Terrestrial planets contain large quantities of ice and jovian planets do not.
Can you see the surface of Venus with a telescope?
Because Venus is so bright, you can easily see it with the naked eye even in very light polluted areas. And you can see it with binoculars. The best way is with a telescope. Even a small telescope, say 60 mm in aperture, can show you Venus and allow you to see it go through its phases.
How do you see Venus through a telescope?
Use a telescope of at least 60mm (2.4”) aperture or greater with at least 50x magnification to observe the planet and note any changes over time. Adding a Moon filter or other colored filters is helpful in reducing the amount of glare and light scatter that Venus emits, while also boosting contrast.
Why is it difficult to operate a spacecraft on the surface of Venus?
Exploring the surface of Venus is difficult because of the intense heat and crushing air pressure. The longest any spacecraft has survived on the surface is a little over two hours – a record set by the Soviet Union's Venera 13 probe in 1981.
How has Venus surface been studied?
It has been studied via ground-based observations and by spacecraft. More than 20 missions, including fly-byes, orbiters, descent probes, atmospheric balloons, and landers have studied Venus.
Why can’t astronomers see the surface of Mars clearly but not the surface of Venus?
When compared to Venus, the surface of the Mars is more visible because it contains a thin atmosphere. On the contrary, Venus has a thick atmosphere which makes the surface quite difficult to see.
How do astronomers observe the surface of Venus?
Thick clouds cover Venus, hiding its surface from view. Since the 1960s, astronomers have used radio waves, transmitted from antennas on Earth or on satellites orbiting Venus, to penetrate the clouds and map the planet. The resulting images reveal surface roughness, density, and slope, but not color.
Has atmospheric pressures at its surface that are roughly comparable to those at Earth’s surface?
Earth Space

|---|---|
| __ are found both on Mars and Earth? | Erosional features to flowing water |
| The surface features ___ are known only through satellite radar mapping? | Venus |
| __ is a moon on Mars | Phobos |
| __ has atmosphere pressure at its surface that are roughly comparable to those at Earth's surface | Saturn's Moon |
Who created the Moon?
The prevailing theory supported by the scientific community, the giant impact hypothesis suggests that the moon formed when an object smashed into early Earth. Like the other planets, Earth formed from the leftover cloud of dust and gas orbiting the young sun.
What is the principal gas in the Venusian atmosphere and also a minor component of the atmospheres of Earth and Mars quizlet?
Carbon dioxide is the major gas in the atmosphere of Venus. ________ are small, extraterrestrial particles that glow brightly and burn up as they travel through Earth's atmosphere. The high surface temperatures of this planet have been attributed to the greenhouse effect.
Which of the following is thought to explain why Venus has so much more atmospheric gas than Earth?
Venus has gained much more gas through outgassing than has Earth. Earth has lost much more gas to thermal escape than has Venus. Because of its lack of magnetic field, Venus has been able to gain gas through the impacts of solar wind particles, while Earth has not gained gas in this way.
What problems would you have if you tried to land on the surface of one of the Jovian planets?
Jupiter is made of mostly hydrogen and helium gas. If you tried to land on Jupiter, it would be a bad idea. You'd face extremely hot temperatures and you'd free-float in mid-Jupiter with no way of escaping.
Why could the Jovian planets grow to be much larger than the terrestrial planets quizlet?
For the Jovian planets, they were made at temperatures that were too low to support rocky compositions. Their ability to hold hydrogen gas allowed them to accrete and become much larger.
How do terrestrial and giant planets differ list as many ways as you can think of?
Terrestrial planets lie closer to the Sun. They are small compared to the giant planets, have relatively high densities, and are made of mostly silicates and metals. The giant planets lie farther from the Sun and are large compared to the terrestrial planets.
Why is it difficult to see Venus through a telescope?
Venus is covered with clouds which are highly reflective. To the naked eye, in binoculars, and in a telescope it appears as a bright ball. It shines brighter than any star in the sky. However, because of these clouds, you won't be able to see the venus's surface.
Can you see Venus during the day with a telescope?
At its best, Venus is brighter than all other celestial objects except the sun and moon. Right now, the brilliant planet is so bright that you can actually see it in the daytime, if you know where to look. Venus doesn't make any visible light of its own. It shines by reflecting sunlight.
Is it safe to look at Venus telescope?
Never attempt to view Venus during these conjunctions with your naked eyes through a binocular or a telescope. It is extremely dangerous and not worth the risk of accidentally blinding yourself and causing permanent eye damage. Venus should be viewed when located safely away from the Sun, like during its elongations.
Has any probe landed on Venus?
Yes, several landers from the former Soviet Union have landed on Venus. They were only able to send us information for a short time because the extremely high temperature and pressure on the surface of Venus melted and crushed the landers.
Which of the following most likely explains why Venus does not have a strong magnetic field quizlet?
Which of the following most likely explains why Venus does not have a strong magnetic field? Its rotation is too slow.
