Mercury’s surface resembles that of Earth’s Moon, scarred by many impact craters resulting from collisions with meteoroids and comets. … Most of Mercury’s surface would appear greyish-brown to the human eye. The bright streaks are called “crater rays.” They are formed when an asteroid or comet strikes the surface.
In which way is Mercury unique quizlet?
Mercury is the closest planet to the Sun and is also the smallest of the eight planets in our solar system. For every 2 orbits of the Sun, which takes around 88 Earth days, Mercury completes three rotations of its axis. It is gravitationally locked and this rotation is unique to the solar system.

What is in the Mercury?
Mercury appears to have a solid silicate crust and mantle overlying a solid, iron sulfide outer core layer, a deeper liquid core layer, and a solid inner core. The planet’s density is the second highest in the Solar System at 5.427 g/cm3, only slightly less than Earth’s density of 5.515 g/cm3.What are 5 facts about mercury?
Facts about Mercury
- Mercury does not have any moons or rings.
- Mercury is the smallest planet.
- Mercury is the closest planet to the Sun.
- Your weight on Mercury would be 38% of your weight on Earth.
- A solar day on the surface of Mercury lasts 176 Earth days.

Is Mercury a cold planet?
On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm. The temperature can drop down to minus 300 degrees Fahrenheit. Sunlight never reaches into the bottoms of some craters near Mercury’s poles.Is Neptune bigger than Mercury?
Neptune is the 4th largest planet in the Solar System, after Jupiter, Saturn, and Uranus. It’s much larger than the terrestrial planets: Mercury, Venus, Earth and Mars. The diameter of Neptune is 49,500 km. … That’s approximately 3.9 times the diameter of Earth.Why is Pluto not a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”What is the diameter and mass of Mercury?

How do you find the diameter of a model?
To figure the scaled diameter for your model, divide the Actual Diameter by 500 to get the diameter of the planet you are drawing in millimeters. Mercury has been done for you. 3. Convert the number of millimeters of the scaled diameter to centimeters by dividing the number of millimeters by 10.
What is the diameter of Mercury compared to Earth?
Mercury’s diameter is 3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan. But it’s not going to stay that size; the tiny planet is shrinking.How do you draw a scale drawing of the solar system?
In which way are Mercury and Venus similar?
The composition of Venus and Mercury is similar, they’re both terrestrial planets made of rock and metal. Mercury is more dense than Venus and thought to consist of 60-70% metal, with the rest rock. … Both Venus and Mercury are within the orbit of Earth. This means that they’re always located near the Sun in the sky.What is the relationship between distance from the Sun and orbital period?
The further away from the Sun it is, the slower the planet’s orbital speed and the longer its path. Both of those factors result in taking longer to make one complete orbit and a planet having a longer year.What is the relationship between orbital radius a Au and period t years?
If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years, then Kepler’s Third Law says P2 = a3.
Is there Mercury on Mercury?

What does it mean to say that Mercury has a 3 2?
— 3:2 spin-orbit resonance means that Mercury has exactly three rotations for every two revolutions.
How does Mercury name offer a clue to one of its defining characteristics?
They named them after their most important gods. Because Mercury was the fastest planet as it moved around the Sun, it was named after the Roman messenger god Mercury. Mercury was also the god of travelers. According to myth, he had a winged hat and sandals, so he could fly.
