Keeping this in consideration,What is a solar diameter?

865,370 mi太阳 / 直径

Also asked,Is the solar system 1 AU in diameter?

We took the radius of the solar system to be 39.5 AU, which means it has a diameter of 79 AU. This means you could put the Solar System about 3440 times between the Sun and the nearest star taking this definition.

Furthermore,How big is the size of the solar system?

The diameter of the Solar System is 100000 times the distance from the Sun to the Earth. Light would from the Sun would take about 555 days to reach the edge of the Solar System compared to 8.25 minutes to reach the Earth.

### What is the diameter of the Earth?

### Which planet has an equatorial diameter of 120 536 km?

Because the four giant planets have no solid surface in their outer layers, by convention the values for the radius and gravity of these planets are calculated at the level at which one bar of atmospheric pressure is exerted. By this measure, Saturn's equatorial diameter is 120,536 km (74,898 miles).
