Mars and Mercury will be less than a degree apart in the sky - this may be VERY difficult to view with the naked eye due to their proximity to the Sun.

The Moon’s distance from Earth varies throughout its monthly orbit because the Moon’s orbit isn’t perfectly circular. Every month, the Moon’s eccentric orbit carries it to apogee – its most distant point from Earth – and then, some two weeks later, to perigee – the Moon’s closest point to Earth in its monthly orbit. - earthsky.org
Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, FRS, HonFRSE (30 August 1871 – 19 October 1937) was a New Zealand-born British physicist who came to be known as the father of nuclear physics. Encyclopædia Britannica considers him to be the greatest experimentalist since Michael Faraday (1791–1867). He also spent a substantial amount of his career abroad, in both Canada and the United Kingdom. In early work, Rutherford discovered the concept […]
