The Exciting Discovery Of 2004 FH: A Record Close Approach

Introduction

On March 18, 2004, astronomers made a stunning discovery as an asteroid named 2004 FH passed within 26,500 miles (42,600 kilometers) of Earth. This marked the closest encounter with an asteroid ever recorded. This exciting discovery provided invaluable insights into the nature of asteroids and their potential danger to our planet.

The Significance of Close Approaches

The Threat of Asteroid Impacts

Asteroid impacts have played a significant role in the history of our planet, with potentially devastating consequences. Therefore, it is essential to closely monitor near-Earth asteroids and track their trajectories to ensure that they do not pose a threat to our planet.

The Value of Close Approaches

Close approaches offer astronomers a unique opportunity to study asteroids up close. By studying the size, shape, and composition of asteroids during close encounters with Earth, we can learn more about the formation and evolution of these celestial bodies.

The Importance of 2004 FH

The close approach of 2004 FH was particularly significant because it provided scientists with an unprecedented opportunity to study an asteroid of this size up close. Measuring between 30 and 100 feet (9-30 meters) in diameter, 2004 FH offered insights into the characteristics of asteroids that could pose a threat to Earth.

The Discovery of 2004 FH

Observation and Tracking

2004 FH was first observed on March 15, 2004 by the NASA-funded Catalina Sky Survey in Arizona. After initial observations, astronomers realized that the asteroid would make a close approach to Earth just three days later.

The Closest Recorded Approach

On March 18, 2004, 2004 FH passed within 26,500 miles (42,600 kilometers) of Earth. This marked the closest approach to Earth by an asteroid ever recorded.

Size and Characteristics

Based on observations during the close approach, astronomers were able to estimate that 2004 FH was between 30 and 100 feet (9-30 meters) in diameter and had an irregular shape. The asteroid's closeness allowed scientists to study its surface features and composition in detail.
