The article from CambridgeToday discusses a range of astronomical events and phenomena, primarily focusing on mini-moons and comets. It also provides a brief introduction to stargazing for beginners.
Mini-moons are small asteroids that are temporarily captured by Earth’s gravity. They orbit around our planet for a short period of time before continuing their journey through the solar system. The first mini-moon to be discovered was 2006 RH120, which orbited Earth for about a year from 2006 to 2007. In 2020, a new mini-moon, named 2020 CD3, was discovered. It is only about the size of a small car and was captured by Earth’s gravity for about three years before it was discovered.
The article also mentions Comet Leonard, which is expected to be visible to the naked eye in December 2021. This comet was discovered by Gregory J. Leonard, a senior research specialist at the Lunar and Planetary Laboratory of the University of Arizona. It will be one of the few comets in recent years that can be seen without a telescope.
The article further explains the difference between comets, asteroids, and meteors. While they are all small celestial bodies, they differ in their composition and behavior. Comets are made of ice and dust and have a tail of gas and dust particles that point away from the sun. Asteroids are rocky or metallic objects that orbit the sun, and meteors are small particles from comets or asteroids that burn up when they enter Earth’s atmosphere.
For those interested in stargazing, the article recommends using binoculars to start with, as they are easier to handle and less expensive than telescopes. Star charts, which can be found online, can also be helpful for identifying constellations and planets. The article also suggests joining a local astronomy club or taking a course in astronomy to learn more about the night sky.
In conclusion, the article provides a fascinating overview of mini-moons and comets, as well as some helpful tips for those interested in stargazing. Whether you’re an experienced astronomer or a beginner, there’s always something new to discover in our vast and mysterious universe.
