Comet 217P/NEAT (also known as 217184 A1 or Neujmin-Prevital-Swift-Tuttle) is a short-period comet discovered on July 12, 2001, by the Near-Earth Asteroid Tracking system (NEAT) at the Palomar Observatory in California. This comet has a well-defined 5.5-year orbital period with a perihelion, or closest approach to the Sun, occurring at a distance of approximately 1.5 astronomical units (AU). One AU is the average distance from the Earth to the Sun, which is about 93 million miles or 150 million kilometers.
The comet's orbital inclination is at about 12.6 degrees to the ecliptic plane, and its orbital eccentricity is relatively low at 0.23, indicating a relatively circular orbit. The comet's aphelion, or farthest point from the Sun, occurs at a distance of around 2.7 AU.
Comet 217P/NEAT is classified as a Jupiter family comet, which means it is related to Jupiter's orbital resonance and has a relatively small nucleus size, likely measuring between 2 and 5 kilometers in diameter. This comet has a relatively short orbital lifetime, estimated to be around 3.5 million years, due to its close approach to Jupiter, which can perturb its orbit and potentially send it on a collision course with the Sun or eject it from the inner solar system.
When Comet 217P/NEAT approaches the Sun, it develops a bright coma, or gaseous envelope, and a tail, which can extend for millions of kilometers. The coma is primarily composed of water ice, carbon dioxide, and other volatile substances that evaporate when the comet is heated by the Sun. The tail consists of ionized gases and dust particles that are propelled away from the comet by the solar wind.
The last observed close approach of Comet 217P/NEAT to the Sun occurred on August 13, 2019, when it reached a perihelion distance of 1.53 AU. During this apparition, the comet reached an apparent magnitude of around 10, making it visible to amateur astronomers using moderate-sized telescopes. The next close approach to the Sun is expected to occur in 2025.
Comet 217P/NEAT is an active and fascinating celestial object, providing valuable insights into the composition and origins of comets and the early solar system. Its relatively short orbital period and close approach to the Sun make it an intriguing target for future observational campaigns and potential future manned missions.
Comet 21/Lemmon (217184 A/LEMMON) is a periodic comet discovered in 1969 that has gained some attention due to its relatively bright appearance during its latest approach to the Sun. Here are some potential pros and cons for those considering purchasing merchandise or experiences related to this comet.
Pros:1. Unique astronomical event: Comet 21/Lemmon is a rare and beautiful astronomical phenomenon. Witnessing its bright tail in the night sky can be an awe-inspiring experience for amateur and professional astronomers alike.
2. Educational value: Observing and learning about comets can be an excellent way to expand one's knowledge of astronomy and the universe.
3. Community building: Joining astronomical societies or online forums dedicated to comet observation can help connect individuals with like-minded enthusiasts, fostering a sense of community and shared learning.
Cons:1. Limited viewing window: Comets, unlike stars or planets, are not permanent fixtures in the night sky. The viewing window for Comet 21/Lemmon is relatively short, so those interested in observing it will need to plan accordingly.
2. Equipment requirements: To fully appreciate the comet's beauty, some level of astronomical equipment, such as binoculars or a telescope, may be necessary. This could add to the financial investment required to observe the comet.
3. Weather dependency: Observing comets is subject to the whims of the weather. Clouds, rain, or other atmospheric conditions could potentially hinder or prevent observations.
Conclusion:Comet 21/Lemmon offers a unique and educational astronomical experience that can be both visually stunning and intellectually stimulating. However, the limited viewing window, equipment requirements, and weather dependency can add challenges to the experience.
Recommendation:For those genuinely interested in observing Comet 21/Lemmon, I would recommend investing in a good pair of binoculars or a telescope to maximize the viewing experience. Additionally, joining an astronomical society or online forum can provide valuable resources and guidance for observing the comet. Lastly, planning observations around clear weather windows will help ensure the best possible viewing conditions.
