What are the dark areas of the moon interpreted to be?
These patches are known as maria – a Latin word meaning 'seas'.
Which of the four Galilean moons is the most volcanically active object in the solar system erupting sulfur rich lava?
The names Marius proposed for the moons in 1614 (suggested to him by a fellow astronomer, Johannes Kepler) are the ones we use today — Io, Europa, Ganymede, and Callisto. Io is the most volcanically active body in the solar system. Its surface is covered by sulfur and lava in many colorful forms.
Which of the following is the major difference between the inner planets as a group and the outer planets as a group?
Summary. The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
Which of the following is not one of the inner terrestrial planets?
Explanation. The inner terrestrial planets consist of Mercury, Venus, Earth, and Mars Saturn is part of the outer planets.
How are the Moon’s dark colored areas different from its light colored areas?
dark colored areas of the Moon, covers large areas of the moon, made up of solid or broken rock, more on the near side of the moon. light colored areas of the moon, at a greater altitude, powder made of finely broken rock, more on the far side of the moon.
What does Dark of the Moon mean?
The Dark of the Moon refers to the period in the 29.53 day lunar cycle when the Moon is decreasing, getting darker or “waning.” The dark of the Moon is the period before the New Moon, or from full Moon to the New Moon, which lasts about 14+ days.
What are the 4 Galilean moons?
67 moons orbit the great gas giant Jupiter; of these, the four largest are known as the Galilean moons, having been discovered by Galileo Galilei using his telescope in 1610. The four moons are Io, Europa, Ganymede, and Callisto, in order of distance from Jupiter. (Their names derive from lovers of Zeus.)
What are the four Galilean moons around Jupiter made of?
Like the rest of the Solar System planets, Jupiter formed out of the disc of dust and gas surrounding the young Sun. Once this gas and dust had condensed to form Jupiter, the leftover material coalesced and grew over time to form the Galilean moons.
What was the main factor that contributed to the difference between the inner and the outer planets?
The inner planets lost these very light gases. Their gravity was too low to keep them, and they floated away into space. The Sun and the outer planets had enough gravity to keep the hydrogen and helium.
How do the inner terrestrial planets including Earth differ from outer jovian planets in terms of size composition and density?
They are opposite to terrestrial planets in many ways. Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and have denser cores than terrestrial planets. Jovian planets also have gaseous atmospheres, with the main gases being hydrogen and helium.
Can you land Jupiter?
The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet crush, melt, and vaporize spacecraft trying to fly into the planet.
How many planets have humans landed on?
Only our two nearest neighbours Venus and Mars have been landed on. Landing on another planet is technically challenging and many attempted landings have failed. Mars is the most explored of the planets. Mercury could be landed on but the speeds involved and the proximity to the Sun are challenging.
What are the dark and light areas on the Moon’s surface?
The face of the Moon turned toward us is termed the near side (image at right). It is divided into light areas called the Lunar Highlands and darker areas called Maria (literally, "seas"; the singular is Mare).
Is the Moon’s surface dark?
In reality it is no darker than any other part of the Moon's surface as sunlight does in fact fall equally on all sides of the Moon. It is only 'dark' to us, as that hemisphere can never be viewed from Earth due to a phenomenon known as 'Tidal Locking'.
How can I see Black Moon?
The best place to see the phenomenon is Chile, where the black moon will block up to 54 percent of the sun. Observers farther north will see less of the sun covered, Forbes reports. The event will only be seen from parts of Antarctica, South America, the Pacific Ocean and the Atlantic Ocean, according to People.
Is the Moon dark or light?
The moon only seems bright in the night sky because it is so close to the earth and because the trees, houses, and fields around you are so dark at night. In fact, the moon is one of the least reflective objects in the solar system….Why is the moon so bright?

Which planet has a moon called Titan?
Saturn’s Saturn's largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere. Titan is the second largest moon in our solar system. Only Jupiter's moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth's moon, and larger than even the planet Mercury.
Where is Enceladus?
Saturn About as wide as Arizona, Enceladus orbits Saturn at a distance of 148,000 miles (238,000 kilometers) between the orbits of two other moons, Mimas and Tethys. Enceladus is tidally locked with Saturn, keeping the same face toward the planet.
Which planet besides Earth has been visited by the largest number of robotic spacecraft?
Astronomy Midterm
| Question | Answer |
|---|---|
| The Cassini mission to Saturn consists of: | An orbiter that orbits Saturn and a probe that descended to the surface of Titan. |
| Which planet (besides Earth) has been visited by the largest number of robotic spacecraft? | Mars |
Why is Mars’s surface red?
Well, a lot of rocks on Mars are full of iron, and when they're exposed to the great outdoors, they 'oxidize' and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
What kind of planets formed inside the frost line and explain the reasons why they formed as they did?
Summary: The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.
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.
Which of the following is not a way in which the terrestrial and jovian planets differ?
Which of the following is NOT a way in which the terrestrial and Jovian planets differ? The Jovian planets have orbits that are highly inclined to the ecliptic and do not revolve in the same direction as the terrestrial planets.
Does it rain diamonds on Jupiter?
New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. In fact the planets have the capability to create 1000 tonnes of diamonds a year.
What if you fell into Saturn?
So, if you tried to walk on this part of Saturn, you would sink through its atmosphere. Saturn's atmosphere is very thick and its pressure increases the deeper you go. After a while, you would stop sinking and unfortunately be crushed by the high pressure deeper in Saturn's atmosphere.
Which God is Earth named after?
Earth is the only planet not named after a Roman god or goddess, but it is associated with the goddess Terra Mater (Gaea to the Greeks). In mythology, she was the first goddess on Earth and the mother of Uranus. The name Earth comes from Old English and Germanic.
What happens if you commit a crime in space?
It states that any person who is launched into space or on a celestial body is under the jurisdiction and control of the country who put them there.
What are the dark smooth plains on the moon called?
mare, plural maria, any flat, dark plain of lower elevation on the Moon. The term, which in Latin means “sea,” was erroneously applied to such features by telescopic observers of the 17th century.
Why can I see the dark side of the Moon?
You can generally see the unlit side of the moon when a considerable amount of sunlight is reflected off the earth. This reflected sunlight illuminates the unlit side of the moon. This is referred to as earthshine, and a decent explanation can be found at timeanddate.com.
What are the dark spots on the sun?
Sunspots are dark, planet-size regions of strong magnetic fields on the surface of the sun. They can spawn eruptive disturbances such as solar flares and coronal mass ejections (CMEs). These regions of the sun appear darker because they are cooler than their surroundings.
