A light year is the distance a photon of light travels in an Earth year. This is equivalent to 9,460,730,472,580.8 km just under ten trillion kilometers.
The most distant planet in our solar system is Neptune (Pluto is no longer classified as a planet) which is around 4.55 billion km from the sun. Earth orbits the sun at an average distance of about 150 million kilometers. So Neptune can be anywhere from 4.551 billion km to 4.553 billion km from Earth at any given time.
Voyager 1, the farthest man-made object, which is now positioned on the outer edge of our solar system, and much more distant than any of our solar systems planets is about 14.6 light-hours from Earth. As a basis for comparison, the Moon is about 1.4 light-seconds from Earth, the sun is approximately 8.5 light-minutes away, Pluto is about 5.5 light-hours.
These distances are well under 1 light year. Although there are many extra-solar planets (planets which are outside of our solar system) which are much farther than 1 light year. The nearest star is 4.3 light-years away.

We are a light-year away from our destination.The newly discovered, earth-like planet is a light-year away from us.
Actually, the sun is only 8 light minutes away from Earth, not 1 light year. A light year is the distance light travels in a year, which is about 9.5 trillion kilometers, while the distance between the Earth and the sun is about 150 million kilometers.
The closest planet to Earth is Venus, which can be between 38 million and 261 million kilometers away depending on where the planets are in their orbits. In light years, this distance is about 0.0000026 to 0.000018 light years.
The moon is about 1.278 light-seconds from Earth.Converting that figure to the equivalent fraction of a year, I get0.000 000 040 486 light-year (rounded)
Kepler-22b is located approximately 600 light-years away from Earth. A light-year is a unit of distance that is the distance light travels in one year in the vacuum of space. The exact distance can vary slightly due to the constantly changing positions of the two planets.
All of the planets in our Solar System are less than a light year away, but no other planets around other stars are within that distance.

Actually, the sun is only 8 light minutes away from Earth, not 1 light year. A light year is the distance light travels in a year, which is about 9.5 trillion kilometers, while the distance between the Earth and the sun is about 150 million kilometers.
The planets that orbit the sun change in distance based on their orbits, but are the only planets that have relatively consistent distance from the sun. These distances are measured in Astronomical Units, the average distance between the earth and the sun. Of these, the one that's furthest away isn't even close to a light-year away from the sun, as Pluto averages 39.5 AU, and 1 light-year is 63,239 AU.
The closest planet to Earth is Venus, which can be between 38 million and 261 million kilometers away depending on where the planets are in their orbits. In light years, this distance is about 0.0000026 to 0.000018 light years.

Some planets can be seen from the earth at certain times. Volcanoes in some planets erupt and the ash surrounds the gas clouds so it seems darker to us. But at different times of year we can see the planets brighter. That is because because of the sun's light. Planets do not have their own light. So they reflect the light of the sun, the big ball of fire.
The order of the planets by longest year is the normal order (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The farther away a planet's orbit is from the Sun, the longer the year.
A light year - is the distance a pulse of light would travel in an earth 'year'. This equates to a distance of5,869,713,600,000 mile in a single year. Something 10,000 light years from earth would be at a distance of58,697,136,000,000,000 miles - or roughly 58,697 BILLION miles away!
