Well it depends what "it" means if your talking about the earth, search "How far is the Earth from the Sun?" If you mean a planet, search same question as the earth one except use the planet in place of the earth.
You can approximate Earth's orbit as a circle, and therefore use the formula for the circumference of a circle. The radius is the distance Sun-Earth (150 million kilometers).
Astronomers use complex calculations to determine celestial bodies' distance.They've stated that the sun is 150 million kilometers far away from the Earth.
" year "
All other stars are to far away to effect earth with heat.
they all have something to do with light but the earth shares the light with the sun as does the moon but on earth we have adapted from just using the sun and use man made light sources.ok?
Astronomical units. (It's 1 from the earth to the sun)
Earth's distance from the Sun is about 93 million miles; since the orbit is very nearly circular, you can use the formula for a circle (circumference = 2 x pi x radius).
To convert a planet's distance from the sun to Earth units, you can use the astronomical unit (AU) as a standard unit of measurement. 1 AU is approximately the average distance from the Earth to the Sun, which is about 93 million miles or 150 million kilometers. You can calculate the distance from the sun to a planet by expressing it in AU based on this conversion.
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
The name we use for Earth orbiting the Sun once time is, "Year". It takes one year for the Earth to revolve once around the Sun.
The distance from the Sun to the Earth is 93,000,000 miles. When discussing distances within the solar system, it is often convenient to use this distance as a comparison. So astronomers use the distance from the Sun to the Earth as 1 "Astronomical Unit", or AU. So 31.95 AU is 31.95 times 93,000,000 miles, or a little more than the distance from the Sun to the planet Neptune.
