SOLAR SYSTEM

Detailed explanation-1: -One astronomical unit is defined as the distance from Earth to the Sun. The distance from the Sun to Mercury is 0.39 AU, to Venus is 0.72 AU, to Earth is 1.00 AU, to Mars is 1.52 AU, to Jupiter is 5.20 AU, to Saturn is 9.54 AU, to Uranus is 19.22 AU, and to Neptune is 30.06 AU.

Detailed explanation-2: -In reality, the average distance from the Sun to Mercury is roughly 58, 000, 000 km (35, 000, 000 miles) or 0.4 AU. At this scale, Mercury’s 0.06 mm diameter is scarcely as large as the point of a needle.

Detailed explanation-3: -If you measure by edge of the Sun’s magnetic fields, the end is the heliosphere. If you judge by the stopping point of Sun’s gravitational influence, the solar system would end at the Oort Cloud.

Detailed explanation-4: -From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight 3.2 minutes to travel from the Sun to Mercury.
