By how many orders of magnitude is the distance to the nearest stars greater than the orbital radius of neptune?

As explained below.

Explanation:

Neptune is gas giant tat is 17 times larger than the earth. The nearest star being Alpha Centauri has an average distance of 4.5 billion kilometers from the earth. Neptune is at  4.4 billion kilometers from the earth i.e about 30 Au from the sun and the alpha Centauri a and b are at approx 4.3 billion km from the earth. Thus it has a greater orbital radius than Neptune 15,299 miles with 164.8 years of average distance.

Based on its distance from the Sun, the eight planets of the Solar System are Mercury (57.9 million km), Venus (108 million km), Earth (150 million km), Mars (228 million km), Jupiter (779 million km), Saturn (1,430 million km), Uranus (2,880 million km), and Neptune (4,500 million km).

Further Explanation

The closest distance between the object and the Sun is called perihelion, while the farthest distance from the Sun is called aphelion.

NASA provides data on stars that are close to the sun. Quite a lot, there are 53 stars. Some are in the middle latitudes when viewed from the earth, others are in the north and south of the earth.

For distances under 10 light-years, there are Alpha Centauri, Barnard Star, Wolf 359, Lalande 21185, Sirius, Luyten 726-8, Ross 154. Alpha Centauri can be seen because of its large size.

Six of the eight planets and three of the five dwarf planets are surrounded by natural satellites. Each of the outer planets is surrounded by rings of planets consisting of dust and other particles.
