Yes, an astronomical unit, or AU, is about 149.5 million kilometres.
The average distance from the Sun to the Earth is about 93 million miles. We call that "one Astronomical Unit", or AU for short.
1 astronomical unit (AU)
Its referred to as an astronomical unit or AU.
That is known as an "astronomical unit".
We can use miles or kilometers to measure both the planets size and their distance from each other and the sun. Their distances from the sun can be hundreds of million km or even billions of km for the outer planets, so it can be useful to use astronomical units instead, where 1 AU (astronomical unit ) is equal to the earth - sun distance.
1 astronomical unit (1 AU)
Earth's average distance from the Sun is about 93 million miles (150 million kilometers). Earth follows an elliptical orbit around the Sun, so its distance from the Sun varies slightly throughout the year. At its closest point (perihelion) in early January, Earth is about 91.4 million miles (147.1 million kilometers) from the Sun, while at its farthest point (aphelion) in early July, it is about 94.5 million miles (152.1 million kilometers) away.

The average distance fromEarth to Moon is 384,403 km (238,857 miles). Before you put this answer into your homework you've got to understand that the Moon takes an elliptical path around the Earth. That number, 384,403 km is an average distance that astronomers call the semi-major axis. The Moon can get closer to the Earth and it can get further. At its closest point, known as the perihelion, the Moon is only 363,104 km (225,622 miles). And at its most distant point, called aphelion, the Moon gets to a distance of 406,696 km (252,088 miles).
Well friend, the Earth is roughly about 93 million miles away from the sun. That distance might seem far for us, but in the grand universe, it's just the right distance for us to feel the sun's warmth and light. Just the perfect spot for a little planet like us to call home. Give it a try, paint your own happy little solar system!
the max distance from earth to sun is known as aphelion
The orbit of Mercury is elliptical. This means that its orbit travels the path of an ellipse, and isn't always the same distance from the Sun. When Mercury makes its closest approach to the Sun, astronomers call this perihelion. So, the perihelion of Mercury is 46 million kilometers (29 million miles), or 0.307 astronomical units (1 AU is the distance from the Sun to the Earth). The furthest point of a planet's orbit is called the aphelion. So in the case of Mercury, its furthest point stretches out to 70 million km (44 million miles), or 0.466 astronomical units.
