If you look to the east after sunset, you will notice a bright, reddish-orange object. This is the planet Mars, 4th rock from the Sun. Less than one month ago, Mars was at opposition. This means that it is directly opposite from the Sun, as we view it. This also means that it is very bright, because it is reflecting light directly back to us. Opposition is the planetary equivalent of a full moon.
The diameter of Mars is about 4200 miles, compared to Earth’s diameter of about 8,000 miles and its mass is just 11% of Earth’s. On May 30, Mars was 47 million miles from Earth.
