β 14y agoConsidering that the planet Pluto was not even discovered until 80 years ago, and
that more than 50 moons of Jupiter have been discovered in the past 50 years, and
that no planets were known outside the solar system until about 20 years ago,
there is no way that we have any information to describe the population of moons
in the galaxy.

β 14y agoFrom largest to smallest, the planets in our solar system are:JupiterSaturnUranusNeptuneEarthVenusMarsMercury.Ganymede (a moon orbiting Jupiter) and Titan (Saturn's moon) are bigger than Mercury.There are many more large planets outside the solar system.
The number of days in a month are determined by the cycles of the moon.
Considering the number of stars in each galaxy, and the number of galaxies that exist in the universe, and the emerging conjecture that as many as 75% of all stars have planets, the probability of the EXISTENCE of another planet somewhere that is almost identical to Earth is very high. BUT . . . considering the distances involved, and the difficulty of detailed observations and measurements of an object that appears to us to be about the same apparent size as a grain of sand on the surface of the moon, the probability of our FINDING it is minuscule.
The number 406,000 is equivalent to the scientific notation of 4.06 x 10 to the third power.
From Wikipedia, the gravitational acceleration on the Moon (on its equator) is 1.622 m/s2. This is the same as 1.622 N/kg, so you can multiply the mass by this number to get the weight in Newton. (The man's mass, of course, will still be 70 kg on the Moon. His weight will change, but his mass will not change.)
The universe can be organized in various scales: Planetary system (e.g. our solar system) Galaxy (e.g. Milky Way) Galaxy cluster (group of galaxies) Supercluster (groups of galaxy clusters) Observable universe (everything we can potentially observe)
Starting from least to greatest magnitude in size: Earth Sun Solar System Milky Way Galaxy Universe
The universe is organized in a hierarchical structure from largest to smallest as follows: universe, observable universe, galaxy, solar system, planet, moon, and then down to subatomic particles like protons, neutrons, and electrons.
Titan is the second largest moon in the solar system, after Ganymede. It is larger than the planet Mercury and is the only moon in the solar system with a dense atmosphere.
Ganymede is the largest known moon in the Milky Way Galaxy.
Titan is the largest moon of Saturn. The smallest of the eight planets is Mercury.
It goes, the sun, Jupiter, Earth, and the moon.
No. Charon is not a planet; it is the largest moon of the dwarf planet Pluto. The smallest planet is Mercury.
Earth's moon is smaller than the Sun. Earth's moon has a diameter of about 3,474.8 kilometers, while the Sun has a diameter of about 1.4 million kilometers.
Titania (Not to be confused with Titan a moon of Saturn or Triton Neptune's moon) is the largest moon of Uranus. It's the eighth largest moon in the Solar System with a diameter of 1,578 km.It was discovered in 1787 by William Herschel on the same day he discovered Oberon another moon of Uranus.See link for more information.
* Galaxy * Nebula * Star * Planet * Moon However, some moons are larger than planets, and some planets and moons are larger than some stars. A constellation is an imaginary pattern of stars, so one cannot speak of its actual size.
Among the smallest astronomical objects is the neutron star, which is smaller than Earth's Moon, but larger than some. Next would be our Moon, followed by the shrunken White dwarf. Normal stars would then follow, and a galaxy is the largest , being a collection of millions or billions of stars. Neutron Star : as small as 20-24 km Moons : for Earth, 3400 km in diameter White Dwarf star : from about 5000 to 50000 km diameter Galaxies : 2000 to 100000 light-years across
