The distance from Earth to the outer edge of the solar system can vary depending on how it is defined. However, on average, it is often considered to be about 120 astronomical units (AU).
An astronomical unit is the average distance from the Earth to the Sun, approximately 93 million miles or 150 million kilometers. Therefore, 120 AU would be roughly 11.16 billion miles or 17.95 billion kilometers.
If we assume that an object is traveling at the speed of light (c), which is about 186,282 miles per second or 299,792 kilometers per second, we can calculate the time it would take to cover this distance.
Using the average distance of 11.16 billion miles:
Time = Distance / Speed of light Time = 11.16 billion miles / 186,282 miles per second
The result is approximately 59,800 seconds, or about 16.6 hours.
So, it would take roughly 16.6 hours to travel from Earth to the outer edge of the solar system at the speed of light. However, it is important to note that this calculation assumes a direct and unobstructed path, which is not realistic in practice. Additionally, traveling at the speed of light is currently not possible for objects with mass, according to our current understanding of physics.
