Of the inner, rocky, planets, Mercury and Venus have no moons, Earth has one, and Mars has two tiny little ones, called phobos and deimos (fear and hatred). Our moon is actually named Luna.

There are two ways to answer your question - \n\nThe orbit of Venus is closest to the orbit of Earth.\n\nHowever, depending on the current positions of the planets in their relative orbits... Mars or Mercury could be closest to Earth.\n\nToday, it appears that Venus is the closest planet.\n\nTwo months from now, Mercury will be the closest planet to Earth.\n\nSee the attached link for a pretty nifty orbit simulator from the NASA /JPL website.

orbit:    57,910,000 km (0.38 AU) from Sun\n        diameter: 4,880 km\n        mass:     3.30e23 kg\nMercury is the innermost and smallest planet in the solar system, orbiting the Sun once every 88 days. It ranges in brightness from about −2.0 to 5.5 in apparent magnitude, but is not easily seen — its greatest angular separation from the Sun (greatest elongation) is only 28.3° (it can only be seen in twilight). Comparatively little is known about the planet: the only spacecraft to approach Mercury was Mariner 10 from 1974 to 1975, which mapped only 40%–45% of the planet's surface.\n\nPhysically, Mercury is similar in appearance to the Moon as it is heavily cratered. It has no natural satellites and no substantial atmosphere. The planet has a large iron core which generates a magnetic field about 1% as strong as that of the Earth. Surface temperatures on Mercury range from about 90 to 700 K (-180 to 430°C) , with the subsolar point being the hottest and the bottoms of craters near the poles being the coldest.\n\nThe Romans named the planet after the fleet-footed messenger god Mercury, probably for its fast apparent motion in the twilight sky. The astronomical symbol for Mercury, displayed at the top of the infobox, is a stylized version of the god's head and winged hat atop his caduceus, an ancient astrological symbol. Before the 5th century BC, Greek astronomers believed the planet to be two separate objects: one visible only at sunrise, the other only at sunset. In India, the planet was named Budha (बुध), after the son of Chandra (the Moon). The Chinese, Korean, Japanese, and Vietnamese cultures refer to the planet as the water star, based on the Five Elements. The Hebrews named it Kokhav Hamah (כוכב חמה), "the star of the hot one" ("the hot one" being the Sun).

The Solar System or solar system[1] comprises the Sun and the retinue of celestial objects gravitationally bound to it: the eight planets, their 162 known moons,[2] three currently identified dwarf planets and their four known moons, and thousands of small bodies. This last category includes asteroids, meteoroids, comets, and interplanetary dust.\n\nThe principal component of the Solar System is the Sun or Sol (astronomical symbol ); a main sequence G2 star that contains 99.86% of the system's known mass and dominates it gravitationally.[3] The Sun's large mass gives it an interior density high enough to sustain nuclear fusion, releasing enormous amounts of energy, most of which is radiated into space in the form of electromagnetic radiation including visible light. Jupiter and Saturn are the Sun's two largest orbiting bodiesand account for more than 90% of the system's remaining mass. (The currently hypothetical Oort cloud would also hold a substantial percentage were its existence confirmed).[4]\n\nIn broad terms, the charted regions of the Solar System consist of the Sun, four rocky bodies close to it called the terrestrial planets, an inner belt of rocky asteroids, four gas giant planets and an outer belt of small icy bodies known as the Kuiper belt. In order of their distances from the Sun, the planets are Mercury (), Venus (), Earth (), Mars (), Jupiter (), Saturn (), Uranus (), and Neptune (). All planets but two are in turn orbited by natural satellites (usually termed "moons" after Earth's Moon) and every planet past the asteroid belt is encircled by planetary rings of dust and other particles. The planets other than Earth are named after gods and goddesses from Greco-Roman mythology.\n\nFrom 1930 to 2006, Pluto (), the largest known Kuiper belt object, was considered the Solar System's ninth planet. However, in 2006 the International Astronomical Union (IAU) created an official definition of the term "planet".[5] Under this definition, Pluto is reclassified as a dwarf planet, and there are eight planets in the Solar System. In addition to Pluto, the IAU currently recognizes two other dwarf planets: Ceres (), the largest object in the asteroid belt, and Eris, which lies beyond the Kuiper belt in a region called the scattered disc. Of the known dwarf planets, only Ceres has no moons.\n\nFor many years, the Solar System was the only known example of planets in orbit around a star. The discovery in recent years of many extrasolar planets has led to the term "solar system" being applied generically to all the newly discovered systems. Technically, however, it should strictly refer to Earth's system only, as the word "solar" is derived from the Sun's Latin name, Sol. Other such systems are usually referred to by the names of their parent star: "the Alpha Centauri system" or "the 51 Pegasi system".\n\nhttp://en.wikipedia.org/wiki/Solar_system

N0-Venus and Mercury are the only planets that don't, perhaps because being close to the sun reduces the ability to hold onto a moon.

Okay, first of all, the moon nor the sun are planets.  The first answer should sum it up.

Xena is the tenth discovered planet although scientists still debate on whether its a planet or a captured iceball. Nirubu hasnt been officially declared a planet yet. Keep this in mind...the definition of planet or satellite is simply an object that travels in an orbital manner around a star. By the way I believe you meant solar system, not universe. We live in our solar system which resides in the milky way galaxy far out on one of the galaxies radial arms. There are billions of galaxies if not more! Feel small now?

The Moon has a surface area of 152 million square kilometers.\nThe Earth is 13.5 times larger.

None, but there are nine planets in the solar system that Earth is part of.

Solar system  \n\nThe solar system comprises our Sun and the retinue of celestial objects gravitationally bound to it. Traditionally, this is said to consist of the Sun, nine planets and their 158 currently known moons; however, a large number of other objects, including asteroids, meteoroids, planetoids, comets, and interplanetary dust, orbit the Sun as well.

Planets have moons. Damn!

My favourtie planet is Jupiter because it's the largest and yet made up of a lot of gas. I actually like it because of its moons. The 4 main moons are really cool. It's one moon, Io, is the most active object in our solar system. Also, because it's soo close to Jupiter, as it rotates around it fluctuates thus making it's shape change. The other cool moon, Europa is covered in a thin layer of ice and it is believed to have H2O water underneath that ice which would make it the only other place than earth in our Solar System to have H2O. Ganymede and Callisto are two really cool moons to look at.

Here's a whole lot about the planet closest to the Sun in the Solar System:

The total number of known moons of Jupiter now stands at 63, currently the most of any planet in the solar system. Many additional tiny moons may exist that have not yet been discovered.

The Earth is a relatively poor planet so we can only AFFORD one moon. Some larger planets with a thriving interstellar economy can afford several large moons and a few spares. There is a planet in the Goografron galaxy that is so rich everyone has their own moon.  The space around the planet became so crowded that it blocked out their two suns, now their economy is collapsing.  Be thankful we just have one.
