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.

The distance between Earth and Pluto varies as the two planets move around their orbits. When they are closest, they are about 29 A.U. apart; at most, the distance is about 51 A.U. Since light travels about 300,000 kilometers each second, it would take light anywhere between 8 hours and 14 hours to make the round-trip journey to Pluto from Earth.\n\nRadio signals travel at the same speed as light. If you were using radio signals to control a robot on Pluto, you would have to be very patient. If you sent your robot a command to move, the command would arrive at least 4 hours later. Then, if your robot took a picture and sent it back to Earth, it would take at least 4 more hours before you could see that picture! \n\n\n\nAU\n\nAU, which stands for "astronomical unit", is a unit for measuring distance. One AU is the average distance from the Sun's center to the Earth's center. It is equal to 149,597,871 km (92,955,807 miles).\n\nAUs are often more convenient to use than kilometers when measuring large distances such as those in space. In this case kilometers are just too small - it would be like measuring the distance from Boston to San Francisco in inches. AUs simply make a measurement easier to understand and give you something to compare it to.\n\nFor example, Saturn's orbit around the Sun has an average radius of 9.5 AU, which means that Saturn is about ten times farther from the Sun than Earth is. The average distance from the Sun to distant Pluto is about 40 AU. Mercury, the planet closest to the Sun, orbits at an average distance of 0.39 AU.\n\nAUs are generally used for measurements of distances within our Solar System. Distances to stars are much larger, and are expressed in terms of light years. One light year is equal to more than 63,000 AUs. The nearest star, Proxima Centauri, is just over 4 light years away.\n\nAlthough Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics. Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet. The uniqueness of Pluto's orbit, rotational relationship with its satellite, spin axis, and light variations all give the planet a certain appeal.\n\nPluto is usually farther from the Sun than any of the nine planets; however, due to the eccentricity of its orbit, it is closer than Neptune for 20 years out of its 249 year orbit. Pluto crossed Neptune's orbit January 21, 1979, made its closest approach September 5, 1989, and will remain within the orbit of Neptune until February 11, 1999. This will not occur again until September 2226.\n\nAs Pluto approaches perihelion it reaches its maximum distance from the ecliptic due to its 17-degree inclination. Thus, it is far above or below the plane of Neptune's orbit. Under these conditions, Pluto and Neptune will not collide and do not approach closer than 18 A.U. to one another.\n\nPluto's rotation period is 6.387 days, the same as its satellite Charon. Although it is common for a satellite to travel in a synchronous orbit with its planet, Pluto is the only planet to rotate synchronously with the orbit of its satellite. Thus being tidally locked, Pluto and Charon continuously face each other as they travel through space.\n\nUnlike most planets, but similar to Uranus, Pluto rotates with its poles almost in its orbital plane. Pluto's rotational axis is tipped 122 degrees. When Pluto was first discovered, its relatively bright south polar region was the view seen from the Earth. Pluto appeared to grow dim as our viewpoint gradually shifted from nearly pole-on in 1954 to nearly equator-on in 1973. Pluto's equator is now the view seen from Earth.\n\nDuring the period from 1985 through 1990, Earth was aligned with the orbit of Charon around Pluto such that an eclipse could be observed every Pluto day.

Well, within 1 lightyear of earth there isn't anything we know of. The nearest Star is Alpha Proxima (or is Centauri B closer now?) and its around 4.5 light years away.\n\nThere are around 100 stars within 50 lightyears of earth and that number grows as you move away. You wont find any other clusters or galaxies until you get to around 2.5 million light years with the closest Galaxy, Andromeda. - the nearest supercluster is more on the order of 50 million light years.

The moon is closest at about 1/4 million miles, the sun is next, about 93 million miles, and the nearest star is Proxima Centauri, about 4 light years (3,800,000,000,000,000,000 miles)

About 92.9 million miles on average. This is also 147 million kilometers. The actual amount varies over time because the earth's orbit isn't a perfect circle. In astronomical terms, this is *very* close. If you made a scale model with the distance from the earth to the sun as 1 inch, then the distance to the nearest star (other than the sun) would be 4.3 *miles*.

If you mean the point in a planet's orbit at which it is closest to the sun, it's the perihelion. The furthest point from the sun in an orbit is the aphelion.\n\nIf you mean the point on Earth that is closest to the sun, then it varies as the Earth rotates.

what? further than the earth in relation to the sun, would be mars. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and one we cant quite see yet.\nI'm not sure i understand your ?, but i hope this helps. sometime pluto comes closer than neptune, because of the orbits. click on this link, then scole down the page it brings you to.\nhttp://www.sciencemonster.com/planets.html

There are ten planets in our solar system namely mercury,venus,earth mars,jupiter,saturn,uranus,neptune,pluto\nand\n2003-UB313 is the official name of the object that is considered to be a contender for the title of "10th planet". As of August 1st, 2005 the IAU has yet to confirm whether this object will be officially be recognized as the 10th planet in our solar system. This little page will follow events and provide more information when available.\nOfficial Name:  2003 UB313  \nProposed Name:  Unknown\nThe name Xena is rumored to be the name submitted to the IAU for approval, althought there is no official confirmation of the name. "..that was our tongue-in-cheek internal name, never intended for public consumption," says Professor Brown \nDiscovered By: Michael Brown, professor of planetary astronomy at California Institute of Technology (Caltech) and colleagues Chad Trujillo of the Gemini Observatory and David Rabinowitz of Yale University.\n\nFirst photographed in 2003 using a 122cm telescope at the Palomar Observatory. \n \nEstimated Size:  approx 2700 km (1,700 miles) in diameter\nThis is the estimate as of August, 2005. From Wikipedia - Although the object's diameter is not yet well determined, it is estimated to be between 2,390 and 3,550  km . The amount of light it reflects (its albedo ) seems to be quite high, and initial observations show that methane ice is present on the object's surface. Both these properties make it more similar to Pluto than previously discovered large outer solar system planetoids .  \nOrbit: 560 years \nestimated one solar orbit per 560 years.  \nDistance from Sun:\n approx 9 billion miles / 14.4 billion km\nThis is around 100 times the Earth's distance, or 3 times Pluto's distance from the Sun. \nWhere is it Now?  At present, it is near its farthest point from Earth, but in about 280 years, it will be as close as Neptune, (the eighth planet, discovered in 1846).

The inner planets are the 4 planets who's orbits are closest to the sun (Mercury, Venus, Earth, and Mars).  The asteroid belt (and millions and millions of miles) seperates the inner planets from the outer planets.\n\nCompared to the distances in between the outer planets, the inner planets might as well be right next to eachother, the distances really start getting big in the outer solar system.

(to the tune of "Twinkle Twinkle Little Star")\n\nI know the planets one by one\nStarting with the one that's closest to the sun.\nMercury, Venus, Earth and Mars,\nAre the first four among the stars.\nJupiter, Saturn, Uranus, Neptune\nAre the next planets in my tune.\nPluto's the farthest one from the sun.\nI know the planets one by one.\n\nIf you like it choose it as best answer...... It would be a "Thank You" for what I've done.

Scientists recently discovered a (presumed) rocky planet orbiting a small red-dwarf star about 25,000 light years from Earth.  The planet is about 5 times larger in diameter than Earth and revolves around its sun about two and a half times further away than does earth.  Because its sun is smaller and cooler and because it rotates further away than does Earth, the average temperature is about -300 degrees and so probably does not harbor life.
