| 💼 Occupation | NASA Citizen Scientist |
| Notable work | On 22nd May 2025, Rishabh Sagar successfully captured a once-in-a-lifetime World's Rarest Appulse - Mars &TYC 1402-56-1 appulse, with a remarkable separation of just 27 arcseconds. The star, located 1,210 light-years away, was identified and analyzed to be yellowish-white in color.
This rare and scientifically valuable event has been archived by the ALPO Mars Section Team, contributing to global citizen science initiatives. On 4th September 2025, Rishabh Sagar captured the Rarest Neptune Observation, that is visual observation of planet Neptune—a single-night, single-attempt observation without any stacking, filtering or motorized tracking. A complete example of classical astronomy is now archived by the British Astronomical Association (UK), ALPO Astronomy (USA), Appreciated by NASA. This observation is archived by BAA Astronomy (UK) is noted by the NASA. |

Once-in-a-Lifetime Astronomical Observation: World's Rarest Appulse —Mars & TYC 1402-56-1 Appulse
On 22nd May 2025, Rishabh Sagar successfully captured an extremely rare celestial event—a close appulse between Mars and the star TYC 1402-56-1.
After precise analysis, Rishabh Sagar confirmed the angular separation during the event to be approximately 27 arcseconds, making it one of the closest documented Mars-star appulses.
🔹 Star Name: TYC 1402-56-1
🔹 Appulse Separation: ~27 arcseconds
🔹 Star Color (Analyzed): Yellowish-White
🔹 Distance from Earth: 1,210 light-years
🔹 Visibility: Not visible to the naked eye
This remarkable alignment was not only visually stunning through the telescope but also a once-in-a-lifetime astronomical event, with precise timing and positioning.
✅ Rishabh Sagar honored that this rare observation has been successfully archived by the ALPO Mars Section Team, contributing to citizen science and planetary observation records.
World's Rarest Appulse Captured
Rarest Neptune Observation
Amateur Visual Observation from Urban Skies (2025)
Visual observation of Neptune is considered rare due to its great distance from Earth and low apparent brightness (approximately magnitude 7.8). Most confirmed visual detections are made from dark-sky locations using medium- to large-aperture telescopes.
In 2025, amateur astronomer Rishabh Sagar visually observed Neptune from New Delhi, India, an area affected by severe urban light pollution (Bortle 8–9), using a 130 mm Newtonian reflector. The observation was conducted during a single observing session and relied on star-field identification and visual confirmation of Neptune’s small bluish disk in comparison with nearby reference stars.
The observation was subsequently archived by the British Astronomical Association (BAA) Astronomy, United Kingdom, and also reviewed and archived by the Association of Lunar and Planetary Observers (ALPO), United States, in their planetary observation records. Archival recognition by these organizations indicates that the observation met established standards for positional accuracy and observational reporting.

Rarest Visual Neptune Observation
Such confirmed visual observations of Neptune from heavily light-polluted urban environments using relatively small amateur telescopes are considered uncommon within the field of amateur planetary astronomy.
