From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 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 13 minutes to travel from the Sun to Mars.
In the so-called perihelic opposition Mars is closest to the Sun and is particularly close to Earth: Oppositions range from about 0.68 AU when Mars is near aphelion to only about 0.37 AU when Mars is near perihelion.
The table below shows the eight planets and the average distance between them. The AU column is the distance in astronomical units. 1 AU is the distance from the Sun to Earth, which is 149,600,000 km .
26 lip 2024 · To convert from astronomical units to light years, we use the following equation: \footnotesize1\ \mathrm {au}=0.000015813\ \mathrm {ly} 1 au = 0.000015813 ly. Or, in the opposite direction: \footnotesize1\ \mathrm {ly}=63,\!241\ \mathrm {au} 1 ly = 63,241 au.
From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
For example, Mars is 1.5 au from the Sun and Neptune is 30 au from the Sun. Procedures Give students a primer on the size of planets and distances in the solar system, providing examples from the Background section above.
