Core Points - The Leimon Comet, discovered in January this year, is a long-period comet with an orbital period of approximately 1150 to 1350 years, making it a rare astronomical event [3] - The comet is expected to reach its closest point to the Sun on November 8, marking its most active phase during this solar system journey [1][4] - The comet's survival through this close encounter with the Sun is uncertain, as it may either disintegrate or create a bright display of gas and dust if it withstands the solar radiation [3][4] Summary by Sections - **Comet Characteristics** - Leimon Comet is classified as a long-period comet with an orbital cycle exceeding 200 years [3] - It is composed of ice, dust, and other compounds, which can either lead to its disintegration or a spectacular display as it approaches the Sun [3] - **Current Observations** - The comet has been performing steadily since passing its closest approach point on October 21, and it is currently moving towards the Sun [3] - Observers in the Northern Hemisphere have enjoyed its presence, capturing beautiful moments alongside natural landscapes [4] - **Viewing Opportunities** - The predicted brightness of the Leimon Comet is around magnitude 4-5, making it visible in the western sky after sunset [7] - Enthusiasts are encouraged to find dark locations away from city lights for optimal viewing, using small telescopes or binoculars [7]

Core Points - November will feature several astronomical events including a "Supermoon," lunar occultation of the Pleiades, and Uranus opposition, creating a spectacular celestial display in the autumn sky [1][2] Group 1: Supermoon - The "Supermoon" will occur on the evening of November 5, when the moon reaches its perigee and is full, appearing larger and brighter than usual, with a visual diameter of up to 34 arcminutes [1] Group 2: Lunar Occultation - On November 6, a lunar occultation of the Pleiades star cluster will take place, although bright moonlight may hinder visibility, requiring telescopes for optimal observation [1] Group 3: Uranus Opposition - Uranus will reach opposition on November 21, providing the best viewing opportunity of the year as it will be closest to Earth, appearing with a unique blue-green hue in telescopes [2] Group 4: Observation Recommendations - It is recommended to observe these celestial events in locations away from city lights for better visibility, with most phenomena requiring binoculars or telescopes for enhanced viewing, except for the "Supermoon" which can be seen with the naked eye [2]

Group 1 - The article discusses a rare astronomical event where Mercury, Mars, and the crescent moon will closely "gather" in the southwestern sky at sunset on October 23, described as a "double star and crescent moon" phenomenon [1][6] - Mercury and Mars are well-known planets, with Mercury being the closest planet to the Sun, often hidden in its glare, making it difficult to observe except during its greatest elongation [1][2] - The event will occur shortly before Mercury's eastern elongation on October 30, which is noted to be the last opportunity for observing Mercury this year, although conditions will be poor due to its low altitude of less than 10 degrees above the horizon [2] Group 2 - Mars will be positioned highest in the sky during the event, followed by Mercury, with the crescent moon being the lowest [6] - Observers are encouraged to find a flat, unobstructed area for viewing, as the low altitude of the celestial bodies and their proximity to the horizon will make them challenging to see without binoculars [6] - The visibility of this event is limited due to the short observation window and the influence of sunlight, making successful observation a rewarding challenge [6]

Core Viewpoint - The C/2025 A6 (Lemmon) comet, with a 1300-year orbital period, has gained public attention as it approaches its perihelion, providing a rare opportunity for observation in various regions of China during dawn and dusk [1][4]. Group 1 - The Lemmon comet is expected to pass its perihelion on November 8, 2025, and will be visible in the early morning and evening skies in most parts of China [1][4]. - The comet is likely a long-period comet originating from the Oort Cloud, which contains billions of primitive small celestial bodies [2][3]. - Initial brightness expectations for the comet were low, but it has exceeded these expectations since early July, leading to increased global interest and successful observations by astronomy enthusiasts [4]. Group 2 - The comet's nucleus appears green with a long, pale blue tail, making it visually distinctive [4]. - Observers in the northern hemisphere can see the comet in the eastern sky before sunrise until October 20, after which it will be visible in the western sky after sunset [4]. - Visibility of the comet will vary slightly by region, and it will become increasingly difficult to observe after its perihelion [4].

Core Viewpoint - On October 21, a rare astronomical event will occur where Mercury and Mars will appear together in the southwestern sky after sunset, providing a unique opportunity for the public to observe this "celestial date" [1][15]. Summary by Sections Definition of "Conjunction" - In astronomy, "conjunction" refers to two celestial bodies having the same geocentric right ascension or geocentric ecliptic longitude. This is a visual phenomenon where the planets appear to come together from Earth's perspective, although they are actually far apart in their respective orbits [4]. Frequency of Conjunctions - Planetary conjunctions are relatively common, but the frequency varies among different planets. Mercury, being the closest planet to the Sun, has a maximum angular distance of only 28 degrees from the Sun. Mars has an average conjunction cycle of about 780 days, during which it approaches the Sun once, allowing for potential conjunctions with Mercury [7][8]. Observational Conditions - Approximately every 780 days, Mars will have a conjunction with Mercury. However, the specific number of conjunctions that can be observed is not fixed due to varying relative positions and speeds of the planets around the time of Mars' conjunction with the Sun [8]. The upcoming conjunction on October 21 is particularly favorable, with both planets having a significant angular distance from the Sun, around 22 degrees, making it a rare observational opportunity [13]. Visibility for the Public - For the public in China, after sunset on October 21, there will be a chance to see the two planets in the southwestern sky, approximately 5 degrees above the horizon. Mercury will have an apparent magnitude of -0.2, while Mars will have a magnitude of 1.5. There will be about a half-hour window for observation, with better conditions in southern regions compared to northern ones. While this celestial event can be seen with the naked eye, using binoculars will enhance the viewing experience [15]. Future Conjunctions - After October 21, there will be four more conjunctions of Mercury and Mars, with one particularly notable event in April 2026, where Saturn will also join, creating a triple conjunction that is highly anticipated [15].

Core Viewpoint - The article highlights the upcoming celestial event of Jupiter and the Moon appearing close together in the sky, referred to as the "star-moon fairy tale," which is expected to be a visually appealing experience for the public on October 14 [2][4]. Summary by Sections - **Celestial Event Description** - The event will occur in the early morning of October 14, where Jupiter and the Moon will be visible in close proximity in the eastern sky, provided the weather is clear [2]. - Jupiter is noted as the largest planet in the solar system and appears very bright from Earth due to its size, despite being far away [4]. - **Observational Conditions** - The Moon will be in its waning phase, appearing as a "D" shape, and will rise from the northeast before coming close to Jupiter, creating a "three-star accompaniment" with two bright stars in the Gemini constellation [6]. - The average distance of Jupiter from Earth is approximately 780 million kilometers, while the Moon is about 384,000 kilometers away, making their apparent closeness a visual coincidence [6]. - **Viewing Recommendations** - To best observe this event, individuals should find an open area facing east and slightly tilt their heads upward. For enhanced viewing, binoculars or small telescopes can be used to see details of Jupiter, such as its cloud bands [8].
