About 250 times greater than it is at the moment, or about the size of Earths orbit. 1 AU.
They are less than 1 AU from the sun.
To convert 1 light-year into astronomical units (AU), you can use the fact that 1 light-year is approximately equal to 63,241 AU. This conversion is based on the distance light travels in one year, which is about 5.88 trillion miles (9.46 trillion kilometers), and the average distance from the Earth to the Sun, which defines one astronomical unit. Therefore, 1 light-year is roughly 63,241 times the distance of 1 AU.
The average distances of the planets from the Sun, expressed in astronomical units (AU) and standard exponential form, are approximately as follows: Mercury: (0.39 , \text{AU} ) or (3.9 \times 10^{10} , \text{m}), Venus: (0.72 , \text{AU} ) or (1.1 \times 10^{11} , \text{m}), Earth: (1.00 , \text{AU} ) or (1.5 \times 10^{11} , \text{m}), Mars: (1.52 , \text{AU} ) or (2.3 \times 10^{11} , \text{m}), Jupiter: (5.20 , \text{AU} ) or (7.8 \times 10^{11} , \text{m}), Saturn: (9.58 , \text{AU} ) or (1.4 \times 10^{12} , \text{m}), Uranus: (19.22 , \text{AU} ) or (2.9 \times 10^{12} , \text{m}), and Neptune: (30.07 , \text{AU} ) or (4.5 \times 10^{12} , \text{m}).
5.2 AU, that is five and one-fifth times as far as the Earth. Saturn is 9.5 AU, Uranus 19 AU and Neptune 29 AU.
There are exactly 77 million AU in 77 million AU!
