The Parker Solar Probe is a spacecraft that has been designed to study the Sun up close. As it approaches the Sun, it experiences intense gravitational forces and high speeds, which can cause time dilation according to Einstein's theory of relativity.
The time dilation effect occurs due to the difference in gravitational potential and relative velocity between two objects. In the case of the Parker Solar Probe, because it gets very close to the Sun and moves at high speeds, time runs slightly slower for the spacecraft compared to observers on Earth.
The exact amount of time dilation experienced by the Parker Solar Probe would depend on its specific trajectory and velocity during its mission. To provide a specific comparison in terms of hours or distance, I would need more precise information about the spacecraft's trajectory and its speed at different points in its journey.
However, it's worth noting that the time dilation effect experienced by the Parker Solar Probe is relatively small and would likely be measured in fractions of a second or minute, rather than a significant time difference of hours.
