What is the correct sequence in the increasing order of heat energy received per unit area from the Sun measured on Earth, Mars and Jupiter?

The amount of solar energy received per unit area, known as solar irradiance or insolation, follows the inverse square law [t1][t4]. This law states that the intensity of radiation is inversely proportional to the square of the distance from the source [t2][t4]. Consequently, as the distance from the Sun increases, the solar flux density decreases significantly [t2]. Earth is located at approximately 1 AU (Astronomical Unit) from the Sun and receives a solar constant of about 1361–1370 W/m² [t2][t4]. Mars, being further away at roughly 1.5 AU, receives much less energy (approximately 43% of Earth's) [t4]. Jupiter, located even further at about 5.2 AU, receives the least amount of heat energy per unit area among the three [t9]. Therefore, the correct sequence in increasing order of heat energy received is Jupiter < Mars < Earth, making Earth > Mars > Jupiter the correct descending representation.
