On 23 July 2021, the world watched as the long overdue and somewhat subdued opening ceremony of the 2020 Summer Olympic Games got underway in Japan. While not the greatest show on Earth, it certainly delivered the greatest Earth on show, for it was the day the Earth appeared over Tokyo. Beamed around the globe …
On 11 July 2021, Sir Richard Branson, founder of Virgin Galactic, took a suborbital flight to the inner edge of outer space, reaching an altitude of 86 km (54 miles) above the surface of the Earth. Although it marked a milestone for space tourism, where that milestone marker should be placed is an ongoing matter …
In 2022, NASA and Arizona State University will send a spacecraft to investigate the unique asteroid 16 Psyche, a metal-rich body about the size of Switzerland orbiting in the asteroid belt at an average distance of 2.9 AU from the Sun.

The lead scaremongerer in the UK is the Daily Express, who started out playfully alerting us to asteroids that will skim by Earth in the coming days.

I once read a quote in a conference abstract that stated the paper had been written to serve as “a historical guide to the asteroid literature for the perplexed”. That quote aptly sums up my desire for writing a piece on the history of asteroid classification and taxonomies, and the schemes currently in use. When …
Many people will remember the day in 2013 when one asteroid stole the limelight from another. On 15 February 2013, all eyes of astronomers were on the close approach of a 30 metre-sized Apollo asteroid 367943 Duende (then known as 2012 DA14).
