Its circular mirror will be 30 m in diameter. In December 2028, Mars will be at its closest approach to Earth (this happens every three years). An astronomer has predicted that, when finished, the telescope will be able to resolve objects that are approximately 2.0 km across on Mars assuming perfect viewing conditions. Approximately how far away is Mars from the Earth when this happens? The dominate wavelengths of visible light coming from Mars are in the range of 500 nm to 700 nm.arrow_forward
