Icarus: The Asteroid That Flies Close To The Sun

Introduction

Asteroids have fascinated humans for centuries. These small, rocky bodies can tell us a lot about the formation of our solar system and provide important clues about our planet's past. One asteroid, in particular, has captured the imaginations of scientists and space enthusiasts alike. Icarus, named after the Greek mythological character who flew too close to the sun, is an asteroid that has a highly eccentric orbit and flies very close to the sun. In this article, we will explore the history and discovery of Icarus, as well as its significance to our understanding of asteroids and the solar system.

The Discovery of Icarus

The Early Observations

Icarus was first discovered on June 22, 1949, by Walter Baade, an astronomer at the Mount Wilson Observatory in California. Baade was studying the outer regions of the solar system when he noticed a fast-moving star-like object that seemed to be in the wrong part of the sky. After studying its path, he realized that it was an asteroid with a highly eccentric orbit that brought it close to the sun. He named it Icarus after the Greek mythological character who flew too close to the sun and had his wings melt.

The Confirmation

It wasn't until 1968 that Icarus was observed again, this time by James Christy and Robert Harrington using the Palomar Observatory in California. They confirmed Baade's discovery and determined that Icarus has a highly elliptical orbit that brings it within 28 million miles of the sun. This is closer than any other known asteroid.

The Significance

The discovery of Icarus was significant because it challenged previous assumptions about the limits of the solar system. Icarus's extreme orbit showed that there could be objects in our solar system that behave in unexpected ways and that our understanding of the solar system was far from complete.

The Orbit of Icarus

The Eccentricity of Icarus's Orbit

Icarus's orbit is one of the most eccentric in our solar system. Its closest distance to the sun is only 28 million miles, while its farthest distance is over 220 million miles. This means that Icarus travels from almost as close to the sun as Mercury to farther out than Mars.

The Stability of Icarus's Orbit

Despite its highly eccentric orbit, Icarus's orbit is surprisingly stable. This is because of a phenomenon called gravitational resonance, in which the gravitational pull of the sun and Jupiter cancel each other out. This keeps Icarus in its current orbit and prevents it from being ejected from the solar system or colliding with another planet or asteroid.

The Exploration of Icarus

Icarus has not yet been explored by a spacecraft, but NASA has plans to launch a mission to study it in the mid-2030s. This mission, called the Icarus Flyby, will use a spacecraft to flyby Icarus and study its surface and composition.

The Importance of Icarus

Icarus's Role in Understanding the Solar System

Icarus's highly eccentric orbit provides important clues about the formation and evolution of our solar system. It shows that there are objects in our solar system that behave in unexpected ways and that our understanding of the solar system is far from complete. Studying Icarus can help us better understand how our solar system formed and the processes that shaped it.

Icarus's Potential as a Resource

In addition to its scientific importance, Icarus also has potential as a resource for future space exploration. It is believed to contain valuable metals such as gold and platinum, which could be mined and used in future space missions.

Icarus's Importance to Space Safety

Icarus's extreme orbit also puts it in a unique position to potentially collide with Earth. While this is unlikely, it is important to study and understand the orbits of objects like Icarus in order to develop strategies to prevent collisions with our planet.
