Is the Moon as dense as Earth?
Not only is the Moon smaller than the Earth, but it is only
about 60 percent as dense as Earth
. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.
Which moon has highest density?
| Name | Io Jupiter I | Density (g/cm 3 ) | 3.528 | Semi-major axis (km) | 421800 | Orbital period (days) (relative to Io) | 1.769 (1) | Inclination (°) | 0.050 |

Which is bigger sun or moon?
The sun and the moon
are about the same size when you look at them in the sky, though that’s just thanks to the coincidence that the sun is about 400 times farther away than the moon and also about 400 times bigger. Another fun coincidence is that the radius of the sun is about twice the distance to the moon.
Who is bigger moon or Earth?
The moon is
a bit more than one-fourth (27 percent) the size of Earth
, a much larger ratio (1:4) than any other planets and their moons. … Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. The moon’s equatorial circumference is 6,783.5 miles (10,917 km).
What is the temperature on the moon?
Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon’s surface, the temperature
can reach 260 degrees Fahrenheit
(127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
Which planet is the slowest to orbit the sun?
A Year On
Venus
:
In fact, Venus takes 243 Earth days to rotate once on its axis – the slowest rotation of any planet – and its rotation is retrograde to its orbital path.
What is the pressure on the moon?
Ambient pressure on the moon is in the range of
l0 -12 torr (night) to l0 -~° torr (day)
.
Why is Mars density so low?
The gravity of Mars is a natural phenomenon, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it.
It is weaker than Earth’s gravity due to the planet’s smaller mass
.
What is the densest planet in the universe?
Astronomers have found what may be the biggest rocky planet in the neighborhood. The planet is called
55 Cancri e.
It is 60 percent larger than the Earth, eight times as massive and orbits its star so fast that an entire year passes in less than a day.
What is the hottest planet?
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
What are the 4 Galilean moons?
A comparison “portrait” of Jupiter’s four Galilean moons
Io, Europa, Gany- mede, and Callisto
, each with different characteristics.
What is the largest moon?
One of Jupiter’s moons,
Ganymede
, is the largest moon in the Solar System. Ganymede has a diameter of 3270 miles (5,268 km) and is larger than the planet Mercury. It has a rocky core with a water/ice mantle and a crust of rock and ice. Ganymede has mountains, valleys, craters and old lava flows.
What is Jupiter’s biggest moon?
Ganymede
. Ganymede is the largest satellite in our solar system. It is larger than Mercury and Pluto, and three-quarters the size of Mars. Harpalyke was discovered Nov.
