SUMMARY
The discussion centers on calculating the gravitational potential energy of a comet with a mass of 1.2x1010 kg at aphelion, where its distance from the Sun is 50 AU. The gravitational potential energy (U) can be calculated using the formula U = -G(m1*m2)/r, where G is the gravitational constant, m1 is the mass of the Sun (1.99x1030 kg), m2 is the mass of the comet, and r is the distance in meters (7.4807x1012 m for 50 AU). The initial attempt incorrectly calculated the gravitational force instead of potential energy, highlighting the need to apply the correct formula for energy calculations.
