Origins & Early Life

Tempel 1 (official designation: 9P/Tempel) is a Jupiter-family comet discovered by Wilhelm Tempel in 1867. It completes an orbit of the Sun every 5.6 years. Tempel 1 was the target of the Deep Impact space mission, which photographed a deliberate high-speed impact upon the comet in 2005. It was re-visited by the Stardust spacecraft on 14 February 2011, and came back to perihelion in August 2016.

Career & Major Achievements

On 26 May 2024, it made a modest approach to Jupiter at a distance of 0.55 AU (82 million km), which lifted the perihelion distance. 9P will next come to perihelion on 12 February 2028 when it will be 1.77 AU (265 million km) from the Sun. Tempel 1 was discovered on April 3, 1867, by Wilhelm Tempel, who was working at Marseille.

Enduring Legacy & Impact

At the time of discovery, it approached perihelion once every 5.68 years (designations P/1867 G1 and 1867 II). It was subsequently observed in 1873 (P/1873 G1, 1873 I, 1873a) and in 1879 (1879 III, 1879b). Photographic attempts during 1898 and 1905 failed to recover the comet, and astronomers surmised that it had disintegrated, when in reality, its orbit had changed.

Historical Fact-Check Quiz: Tempel 1

True or False: “Tempel 1's orbit is highly variable due to gravitational influences, making it a key subject for studying long-period celestial mechanics.”

Answer (TRUE ⭕): The comet's path is significantly altered by the gravitational pull of Jupiter, which is a major factor in its orbital evolution.
