What is the distance between the Earth and the Sun called?
astronomical unit
astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).
Who is Earth’s sister planet?
Venus
Venus has long been considered Earth’s twin sister. The two planets are very similar in some respects and share many physical and orbital characteristics: inner planets.
How long is a light year in Earth years?
about 6 trillion miles
A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.
What is the greatest distance from the Earth to the Sun?
The exact difference in the distance between Earth’s closest and farthest points from the sun is 3,104,641 miles (4 996 435 km), or 3.28 percent, which makes a difference in radiant heat received by the planet of nearly 7 percent. The average distance between the Earth and sun is about 93 million miles (150 million km).
What accurately describes Earth’s distance from the Sun?
Earth’s orbit around the sun is presently circular and therefore Earth is always equidistant from the sun throughout the year. Earth is closer to the sun in January (perihelion) and farther away in July (aphelion). The Earth-Sun distance averages 150 million kilometers (93 million miles).
Is the Sun a perfect distance from Earth?
The Sun is 93 million miles (150 million kilometers) from Earth. Its nearest stellar neighbor is the Alpha Centauri triple star system: Proxima Centauri is 4.24 light years away, and Alpha Centauri A and B-two stars orbiting each other-are 4.37 light years away.
What is the mean distance of the Earth from the Sun?
Astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).
