Is the solar system 1 AU? As noted earlier, Earth’s average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. That’s 1 AU. Mars is on the three-yard line of our imaginary football field. How...
How big are we compared to the solar system? The Solar System is about 36 billion times larger than Earth (3.6 X 10^10). How big is our solar system compared to Milky Way? Most commonly, our solar system in its entirety...
What is the size of our solar system in light years? Now 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...
How big our solar system really is? Looking at the aphelion(according to NASA figures) of the orbit of the farthest acknowledged planet, Neptune, the Solar System would have a radius of 4.545 billion km and a 9.09 billion km diameter. How...
Is the solar system bigger than a light-year? 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. The Light Year is fine for measuring...
Why is the Oort Cloud important? The Oort cloud is the proximate source of observed nearly parabolic, so-called ‘new’ comets entering the planetary region, and is also the presumed source of the long-period comet flux and the majority of Halley-type comets...
What is there after Oort Cloud? Once you get beyond the Oort Cloud, there really isn’t much mass to speak of. The interstellar volume is largely occupied by the appropriately named Interstellar Medium, or ISM. Is Voyager 1 past the Oort...
How far away is the Oort Cloud in light years? The Oort Cloud is about 2 light years away from Earth. This means it takes light – travelling at 300,000 kilometres every second – 2 years to reach Earth from the...
Is the Oort cloud considered part of our solar system? The Oort Cloud is the most distant region of our solar system. Even the nearest objects in the Oort Cloud are thought to be many times farther from the Sun than...
How big is the Oort Cloud in light years? The Oort cloud is an immense spherical cloud surrounding the planetary system and extending approximately 3 light years, about 30 trillion kilometers from the Sun. This vast distance is considered the edge...
