Mercury is a planet much like the Moon. It has no atmosphere, and its surface is covered with circular im pact craters and huge, round basins . Most of Mercury looks much like the lunar highlands; apparently it was subjected to the same bombardment that shaped the Moon in primordial times.
What planet is similar to Earth’s moon?
Titan is also tidally locked in synchronous rotation with Saturn , meaning that, like Earth’s Moon, Titan always shows the same face to the planet as it orbits. Saturn takes about 29 Earth years to orbit the Sun (a Saturnian year), and Saturn’s axis of rotation is tilted like Earth’s, resulting in seasons.
Which of the following is a way that the planet Mercury is similar to the moon quizlet?
Which of the following is a way that the planet Mercury is similar to the Moon? Its surface is heavily cratered .
What is similar about Mercury and Earth?
Much like Earth, Mercury is a terrestrial planet , which means it is composed of silicate minerals and metals that are differentiated between a solid metal core and a silicate crust and mantle. For Mercury, the breakdown of these elements is higher than Earth.
Why does the Moon and Mercury look alike?
How are surfaces of Mercury and the Moon Similar different Why quizlet?
Mercury is often compared to the moon because its surface looks similar to the backside of the moon (the main source of erosion for both is meteorite impact). Both have weak magnetic fields, but mercury doesn’t have any Maria like the moon does. Also, the density of the moon is much less than that of Mercury.
Is Mercury or the moon closer to Earth?
In fact, Mercury is closer to the size of Earth’s moon than it is to planet Earth as Earth’s moon as mean radius of 1,737.1 km. Mercury also resembles Earth’s moon with the surface of the planet featuring extensive plains and catering. Although Mercury is the smallest planet, it is still larger than Earth’s moon.
Does Mercury have moons?
| Planet / Dwarf Planet Confirmed Moons Total | Mercury 0 0 | Venus 0 0 | Earth 1 1 | Mars 2 2 |

Does Mercury have an atmosphere?
Atmosphere and Weather: Mercury has an extremely thin and non-protective atmosphere . For all practical purposes, the atmosphere is nearly a vacuum. The sparse atmosphere is primarily composed of oxygen, sodium and hydrogen. Mercury’s atmospheric atoms are continuously being lost to space.
Which of the eight planets has a similar mass than Mercury?
Venus , otherwise known as “Earth’s Sister Planet”, is so-named because of its similarities in composition, size, and mass to our own. Like Earth, Mercury and Mars, it is a terrestrial planet, and hence quite dense.
Why do we expect Venus and Earth similar?
Why might we expect Venus and Earth to be similar? Both planets are about the same size, density, and have the same chemical composition . ... Venus is too close to the sun to have liquid water oceans and Earth is far enough from the sun to have liquid water oceans.
What is the main reason Mercury is much hotter than the Moon?
What is the main reason Mercury is much hotter than the Moon? Mercury is closer to the Sun . absorb infrared light and transmit infrared light. What would the temperature of a planet be if its reflectivity were 1.0?
How big is Mercury compared to the moon?
With a diameter of 4,879 km (3031.67 mi), Mercury is the smallest planet in our Solar System. In fact, Mercury is not much larger than Earth’s own Moon – which has a diameter of 3,474 km (2158.64 mi).
What is Mercury’s gravity compared to Earth?
| MERCURY EARTH | Mass 0.0553 1 | Diameter 0.383 1 | Density 0.985 1 | Gravity 0.378 1 |

What is the difference between the atmosphere of Mercury and Earth?
Mercury has a low gravity and receives large gusts of solar winds from the nearby Sun. Earth’s atmosphere contains nitrogen, oxygen, argon, carbon dioxide, and a few other molecules. Mercury, on the other hand, contains hydrogen, helium, oxygen, sodium, calcium, potassium, and water.
How does Mercury look like inside?
The planet Mercury looks a little bit like Earth’s moon . Like our Moon, Mercury’s surface is covered with craters caused by space rock impacts. Mercury is the closest planet to the sun and the eighth largest. It has a diameter of 4,880 kilometers.
Why is Mercury the closest planet to the Sun?
Formation. Mercury formed about 4.5 billion years ago when gravity pulled swirling gas and dust together to form this small planet nearest the Sun . Like its fellow terrestrial planets, Mercury has a central core, a rocky mantle, and a solid crust.
How are the polar regions of Mercury and the Moon similar?
How are the polar regions of Mercury and the Moon similar? Both seem to have ice pockets in the deepest, darkest crater floors .
Do Mercury Venus and Earth have similar overall densities?
Mercury, Venus, and Earth have similar densities . The density of Mars is very similar to that of the other terrestrial planets. Venus can appear as a crescent through the telescope. Mercury’s rotation and revolution are an example of a 3:2 resonance.
Why is Mercury closest to Earth?
By using a more accurate method for estimating the average distance between two orbiting bodies, we find that this distance is proportional to the relative radius of the inner orbit. In other words, Mercury is closer to Earth, on average, than Venus is because it orbits the Sun more closely .
Which planet is similar to Earth?
In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
Why is Mercury called Mercury?
Mercury is named after the messenger for their gods . The Roman Mercury had wings on his helmet and shoes. He could travel very quickly from place to place. The planet Mercury moves quickly around the sun.
What planet has 47 moons?
In 2019, twenty new irregular satellites of Saturn were reported, resulting in Saturn overtaking Jupiter as the planet with the most known moons for the first time since 2000.
What if Mercury had a moon?
What if Mercury had a moon? Any Moon that Mercury might have had or tried to capture would be in an unstable orbit because the sun would tug at it . The Moon will eventually either spiral away and orbit the sun or would get dislodged from a stable orbit around Mercury and crash into the planet.
Why doesn’t Mercury have any moons?
Up first are Mercury and Venus. Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn’t be able to hold on to its own moon . Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.
