Moons and Natural Satellites
Natural Satellites, also know as moons, are natural celestial bodies revolving around a bigger object like a planet or a dwarf planet. Some famous natural satellites are our Moon (Luna), Ganymede, Europa and Titan.
601 Questions
What fraction of the moon do we see during a quarter moon?
During a quarter moon, we see half of the moon's surface lit up by the sun. This is because the angle between the sun, Earth, and moon creates a line where we see only half of the illuminated side.
How menny moons does merckary have?
Mercury, not "merckary," has no moons. It is one of the two planets in our solar system without any known natural satellites.
No, Jupiter is not a source of light. It reflects light from the Sun, making it visible from Earth.
What is a planet and the moons that revolve around it called?
A planet and its moons are collectively referred to as a planetary system. The planet is the primary celestial body that orbits a star, while moons are natural satellites that orbit the planet.
What is the smallest moon orbiting any of the terrestrial planets?
Deimos, the smaller of the two moons of Mars, is the smallest moon in the solar system to orbit a terrestrial planet. It is irregular in shape but averages about 12 kilometers or about 9 miles across.
What does the word cosmonant mean in relation with astronomy and who is a cosmonant?
Cosmonaut is the Russian word for astronaut.
What are Jupiter's 4 most important moons?
Jupiter's four most important moons are Io, Europa, Ganymede, and Callisto. They are known as the Galilean moons and were discovered by Galileo Galilei in 1610. These moons are of particular interest due to their varied geology and potential for hosting liquid water beneath their icy surfaces.
How many moons are around a neutron star?
There are no moons around a neutron star. A large, spherical body orbiting a neutron star would be considered a planet.
Was the space race just a race to the moon?
No, the space race was a competition between the United States and the Soviet Union to demonstrate technological superiority in space exploration. While landing on the moon was a significant milestone in the race, both countries were also focused on other achievements such as satellite launches, human spaceflight, and space station development.
What is the number of natural satellites Mars has?
Mars has two natural satellites, Phobos and Deimos.
When does the moon orbit the earth fastest?
The moon orbits the Earth fastest when it is closest to Earth, at the point of its orbit called perigee. This is because the gravitational pull between the Earth and the moon is strongest at this point, causing the moon to move faster in its orbit.
Is Saturn's moon Rhea bigger than Earth's moon?
No, Saturn's moon Rhea is smaller than Earth's moon in terms of both diameter and mass. Rhea has a diameter of about 949 miles (1,527 kilometers), while Earth's moon has a diameter of about 2,159 miles (3,474 kilometers).
None, because Nibiru doesn't exist.
Those that support the Nibiru myth, and believe Nibiru to be a large terrestrial planet (there are many different beliefs among Nibiru believers as to what Nibiru actually is), often claim that it has 18 visible moons.
Does the earth look bright when it is seen from the moon?
From the surface of the Moon, the Earth appears substantially larger than the full moon does from Earth. This would be expected since the Earth's diameter is 4 times that of the Moon. Also, the Earth is always in the lunar sky for the one-half of the Moon that faces Earth, and is never visible from the opposite side. It would always appear to be in almost exactly the same place. It only appears to "rise and set" along a small strip between the two faces of the Moon.
The brightness would vary with the phases, which would be exactly the opposite of the concurrent phase of the Moon: when the Moon is Full, the Earth is new, and vice versa. However, the Earth would be outshone by the Sun for the 14 days of lunar "daylight" in which the Sun and Earth are both always in the sky. This would make the Earth nearly invisible when it was close to the Sun.
Why does the moon have very little water?
Without an atmosphere, water or water vapor will be ionized by the intense solar radiation and become hydrogen and oxygen. The hydrogen is swept away by the solar wind. At low pressures, water's boiling point (vapor point) is very low, and in a vacuum it will rapidly disperse.
The water that does exist on the Moon is found as ice deposited by comets and asteroids. The ice is buried deep within craters near the lunar poles, where sunlight never reaches it.
How long does tit take for the Moon to revolve once around Earth?
It takes about 27.3 days for the Moon to revolve once around Earth.
Does the moon Miranda have dirt or gravel?
Miranda is a moon of Uranus known for its complex surface features. It is believed to have a mix of water ice, rock, and possibly organic compounds on its surface, rather than traditional dirt or gravel. The detailed composition of Miranda's surface is still being studied by scientists using data from space missions.
Is titan larger or smaller than earth?
Overall, Titan is smaller than Earth. Titan has a diameter of about 5,151 kilometers, making it the second largest moon in our solar system. Earth, on the other hand, has a diameter of about 12,742 kilometers.
What is the best classification for a natural satellite?
The best classification for a natural satellite is based on the object it orbits. For example, Earth's moon is classified as a natural satellite because it orbits Earth. Natural satellites can also be classified based on their size or composition.
Does the season affect shadow direction?
Yes, the season can affect the direction of shadows due to the position of the sun in the sky. In the summer, the sun is higher in the sky, resulting in shorter shadows that are cast more directly below objects. In the winter, the sun is lower, leading to longer shadows that are cast at an angle.
Why is the moon tilted different?
The moon's tilt, also known as its inclination, is different from the Earth's tilt because the two bodies formed under different circumstances. The moon's tilt plays a crucial role in shaping its orbit and influencing things like eclipses and tides.
Does Mars have extreme pressure?
No, Mars has a much lower atmospheric pressure compared to Earth. The average surface pressure on Mars is about 0.6% of Earth's atmospheric pressure at sea level, making it too thin to support human life without a pressure suit.
