Radius Of Solar System In Km

It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup. So we will take the average distance between the sun and pluto as the radius of the solar system which is 5913520000 km or 395 au where au stands for astronomical unit 2 orbit of comets beyond the orbit of pluto there are object that orbit the sun.

That number is agreed by most sources to be about 3944 au.

Radius of solar system in km. To compensate we use plutos mean distance from the sun. In our solar system jupiter is the planet with the largest radius of 71492 km it has a mass of 189861027 kg asked in astronomy planetary science stars. Pluto only has a radius of 715 miles 1150 km.

Uranus and neptune are very close in size. This is a difference of 4638 kilometers which is almost twice mercurys radius. Now that is a lot of zeros so lets simplify it into astronomical units.

The final object in the picture is pluto which is now classified as a dwarf planet. It varies slightly from pole to equator due to its rotation. The solar radius is approximately 695700 kilometres 432300 miles which is about 10 times the average radius of jupiter about 109 times the radius of the earth and 1215th of an astronomical unit the distance of the earth from the sun.

It is 14373 billion km from the sun thus giving the solar system a diameter of 28746 billion km. It has a radius of 71492 kilometers at the equator and a radius of 66854 kilometers at the poles. 1 audistance from the earth to the sun equals 149597870691 km.

One au is the distance from the earth to the sun or about 150 million km. Diameter of the solar system. If we use plutos orbit to find the diameter of the solar system there is the problem of plutos elliptical orbit.

Now considered the eighth and final planet in the solar system is neptune the fourth largest planet with a radius of 15389 miles 24766 km. However later studies revealed that icy satellites as large as iapetus 1470 kilometers in diameter are not in hydrostatic equilibrium at this time and a 2019 assessment suggests that many tnos in the size range of 400 1000 kilometers may not even be fully solid bodies much less gravitationally rounded. Looking at the aphelionaccording to nasa figures of the orbit of the farthest acknowledged planet neptune the solar system would have a radius of 4545 billion km and a 909 billion km diameter.
