Additionally,What is the radius of solar system?
695,700 kilometres (432,300 miles) is approximately 10 times the average radius of Jupiter, about 109 times the radius of the Earth, and 1/215th of an astronomical unit, the distance of the Earth from the Sun....Solar radius.

Beside above,How big is the entire solar system?
It is 143.73 billion km from the Sun, thus giving the Solar System a diameter of 287.46 billion km. Now, that is a lot of zeros, so let's simplify it into astronomical units.
Considering this,What is the diameter of the solar system in light years?
about .00127 light yearsNow that you know how far a light year is, consider the fact that the diameter of our Solar System is approximately Page 2 7,440,000,000 miles, 80 AU, or about . 00127 light years.
Likewise,How far is the edge of the solar system?
around 100,000 AUThe outer edge is estimated to be around 100,000 AU. NASA's Voyager 1, humankind's most distant spacecraft, is around 125 AU. Scientists believe it entered interstellar space, or the space between stars, on Aug. 25, 2012.
You might wonder why we don't use this unit when discussing the solar system. The Light Year is about 64,500 times larger than the Astronomical Unit, too large to be appropriate for an object the size of our solar system.
Most commonly, our solar system in its entirety is said to have a diameter of 287.46 billion km, a length which could fit 36 billion Earths. As large as this number sounds, our solar system is in fact over 160 million times smaller than the Milky Way galaxy!
one million EarthsThe sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8% of the solar system's mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
278.8 billion Sun'sThe Solar System is quite huge, as you can fit 278.8 billion Sun's in it.
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
The fastest man-made object we have launched into space is Helios 2 with a speed of 157078 mph. So the time it would take for Helios 2 to reach the edge of our solarsystem is about 59206254,2176 hours or roughly 6759 years.
