What Is Hermes in Astronomy?

Have you ever heard of Hermes in astronomy? If not, don’t worry, you’re not alone.

Hermes is a fascinating asteroid that has been studied by astronomers for decades. In this article, we’ll delve into what exactly Hermes is and what makes it so unique.

What is Hermes?

Hermes is an Apollo asteroid, which means that its orbit crosses Earth’s orbit. It was discovered on October 28th, 1937 by Karl Reinmuth at the Heidelberg Observatory in Germany. The asteroid was named after the Greek god Hermes, who was known as the messenger of the gods in Greek mythology.

Size and Characteristics

Hermes is considered a small asteroid with a diameter estimated to be between 400 and 800 meters. It has an irregular shape and rotates on its axis every 7.1 hours.

What makes Hermes unique is its close approach to Earth. In fact, it has come closer to our planet than any other known asteroid.

Close Approach to Earth

On October 30th, 1937 – just two days after its discovery – Hermes made its closest approach to Earth at a distance of only 800,000 kilometers (about twice the distance from our planet to the moon). This close encounter allowed astronomers to study the asteroid in detail and learn more about its composition.

Future Close Approaches

Since its discovery, Hermes has made several close approaches to Earth. However, none have been as close as its first encounter. The next time it will come close to our planet will be on April 26th, 2276 when it will pass by at a safe distance of about 5 million kilometers.

Conclusion

In conclusion, Hermes is a small but fascinating asteroid that orbits close to Earth. Its irregular shape and unique characteristics make it an interesting subject for astronomers to study.

While it poses no threat to our planet, its close approach in 1937 allowed scientists to learn more about the asteroid and its composition. Who knows what other secrets Hermes may hold?
