Comet Hale–Bopp, one of the brightest comets of the 20th century, reached perihelion around early April. Discovered independently by astronomer Alan Hale and amateur astronomer Thomas Bopp in July 1995, it quickly became a significant object of interest due to its impressive brightness and long tail, which spanned thousands of kilometers. Astronomers predicted its future visibility would attract attention globally, leading to widespread public interest. Throughout its appearance in 1997, Hale–Bopp was visible to the naked eye and easily observed in both the northern and southern hemispheres.

The comet's trajectory brought it close to the Sun, allowing observers to witness its magnificent display. Its close proximity to Earth exemplified the importance of observational astronomy, as it allowed both amateur and professional astronomers to study its dynamics and composition up close. Notable photographs and video footage of the comet were captured by enthusiasts and professionals alike, resulting in an unprecedented level of public engagement with a celestial event.

Furthermore, Hale–Bopp's return to the inner solar system increased interest in the scientific inquiry into cometary bodies and their implications for understanding the Solar System's formation. Comets like Hale–Bopp are considered relics of the early solar system, and studying them helps scientists learn more about the conditions that existed around the time of the formation of planets, including Earth.
