in relation to the other planets in our solar system... our moon is bigger than pluto but smaller than the other planets.\n\nin relation to other moons of other planets in our solar system... it is the 5th largest out of all the other planetary satellites.\n\nthe exact figures are at the link below:\n-(this other link might help as well)

For any planet with a moon, the planet's mass can be approximated by GmM/r² = mv²/r = mrω² = mr(2π/P)², where G is the gravitational constant, m the mass of the moon, M the mass of the planet, r the distance between planet and moon, and P the period of the moon. The mass of the moon cancels out, leaving\nM = r³(2π/P)²/G\n\nThe masses of moonless planets have to be determined by Perturbation Theory, the effect of one planet's orbit on the orbits of other planets.\n\nThe diameter of another celestial object can be estimated by multiplying the angle subtended by the object by its distance from us.  A closer estimate is obtained by\nd/2 = Dsin(α/2) \nwhere d is the diameter, D is distance to the object, and  α is the subtended angle.

The Moon is Earth's only natural satellite. It has no formal name other than "The Moon", although in English it is occasionally called Luna (Latin for moon), or Selene (Greek for moon), to distinguish it from the generic "moon" (natural satellites of other planets are also called moons). Its symbol is a crescent. The terms lunar, selene/seleno-, and -cynthion (from the Lunar deities Selene and Cynthia) refer to the Moon (aposelene, selenocentric, pericynthion, etc.).\n\nThe average distance from the Moon to the Earth is 384,403 kilometers (238,857 miles). The Moon's diameter is 3,476 kilometres (2,160 mi). Reflected sunlight from the Moon's surface reaches Earth in 1.3 seconds (at the speed of light).\n\nThe first man-made object to land on the Moon was Luna 2 in 1959, the first photographs of the otherwise occluded far side of the Moon were made by Luna 3 in the same year, and the first people to land on the Moon came aboard Apollo 11 in 1969.

If your question is : "how much space is in the solar system?" --\n\nThe solar system is a sphere occupying approximately 7.244^29 (7.244 followed by 29 zero's) miles\n\nIf that's not your question then I don't have the foggiest notion of what you're asking.

The average Earth-Moon distance is about 385,000 km.  Remember, the average is important because the moon rotates around the Earth in an eliptical fashion, which means that there are times when the moon is closer to the Earth than others depending on the point in its rotation.

Info below retrieved from Wikipedia\n\nmoon equatorial diameter  = 3,476 km\nearth equatorial diameter = 12,756 km\nThen, the size of the moon compared to earth = 0.27\n\nThe inclination of the Moon's orbit makes it implausible that the Moon formed along with the Earth or was captured later; its origin is the subject of some scientific debate.The current theory on the moon's origin is that a very large object hit the earth some \n 4,527 ± 10 million years ago, causing a large amount of dust to orbit the earth. Eventually the dust accumulated to form the moon. The moon has many minerals which are similar to earth, and the moon lacks an molten iron core.\n\nThe gravity on the moon is very small, about 0.1654 that of earth. This would account for the lack of atmosphere.\n\nThe earth receives about 1,370 watts per square meter of solar energy, of which only about 1,000 watts per square meter reach the surface due to the adsorbtion of heat by the atmosphere.\nSince the moon has no atmosphere, the temperatures on the moon swing higher/lower than the temperatures on the earth.\nThe min, mean and max temperatures on the surface of the moon (in Kelvin) are 40 K,  250 K, and  396 K respectively. The min, mean and max temperatures on the surface of earth are 185 K (-88 °C), 287 K (14 °C), and 331 K (58 °C) max respectively.\n\nThe apparent lack of craters on the earth is due to "plate tectonics", or the movement of the surfaces of the earth. Many craters were swallowed up when, say, the India plate moved underneath the plate which contains the Himalaya mountains.\n\nHope this helps!

Parallax.  By coincidence, the Sun is about 400 times as far away as the Moon and also 400 times the diameter, so it appears about the same size.  If I see a total solar eclipse here in NZ, then anywhere else in the world, the Moon won't be directly in front of the Sun.  For instance, the 1999 total eclipse of the Sun started in Nova Scotia.  Before that, it was only visible from space.   The path of totality crossed the Atlantic, Europe, Turkey, the Middle East, Iran, India and then left the surface of the Earth again.

THe main issue with the Moon being the same size as the earth is that the moon would no longer be pulled in by the earth's gravitional pull. The planets would either settle into seperate orbits or collide and kill us all.\n\nThat aside, the size of Earth is one factor determing wether or not life is supportable. Other important factors are the tilt (has to be within 3 degrees if I remeber correcctly) and it's distance from the sun. \n\nI have heard of the theory of an 'anti-earth', a tehrotical earth on the oppsite side of our orbit with the same chactersitics as our planet and therefore capable of life. This might be starying into the realm oif sci-fi though

Planets and asteroids.\n\nAll the planets in the solar system have a natural satellite except Mercury and Venus. \n\nSeveral asteroids are doubles, which two similarly sized components - so they don't count. But there are cases of asteroids with much smaller companions. So you can call these asteroids with moons.\n\nComplete lists of double asteroids - which includes asteroids with little companions (asteroid moons) is here:\nhttp://hea.iki.rssi.ru/~denis/doublemp.html\nhttp://www.johnstonsarchive.net/astro/asteroidmoons.html

Of course the Moon is closer than the Sun.\n\nThe average distance from the earth to the sun, the semimajor axis of its orbit, is 149,597,890 km.\n\nMoon's orbit is elliptical: its average orbital radius is 384401 km, apogee (farthest distance from the Earth) is 406700 km, and perigee (distance of closest approach to the Earth) is 356400 km.
