"Are Robotic Space Probes the Best Way to Explore the Solar System?"," Naturally, the first thing that comes to mind is the usage of robotic space probe for this task.
Some of the more famously known space probes include the Voyager series as well as the Pioneer series.
Even exotic planets such as Neptune and even Pluto has been photographed by these probes.
Especially after Pluto, Kuiper belt starts and this is a region where many asteroids can be found.
Once you pass these, you enter the heliopause, which is actually considered the boundary of our solar system.
One way to go to these distances is by using robotic space probe.
Usually, radioisotope thermal generators are used in these types of probes to provide enough power for them to function.
Of course, these types of power generations systems can only create enough power for 20 to 30 years and anything beyond that becomes impossible.
In addition, due to the huge distances involved, the amount of energy that is required to send a signal to Earth also becomes a significant factor.
