Executive Summary

  • A potential Planet Nine candidate has been identified by analyzing archival data from the IRAS and AKARI infrared satellites.
  • The candidate displays movement consistent with a distant planet, but its orbit and nature require further confirmation.
  • The discovery has generated debate, with some astronomers questioning whether it aligns with the predicted characteristics of Planet Nine.

Event Overview

Astronomers are investigating a potential candidate for Planet Nine, a hypothetical planet theorized to exist far beyond Neptune. By examining archival data from the Infrared Astronomical Satellite (IRAS) and the AKARI satellite, researchers identified an object exhibiting movement consistent with a distant planet. While the discovery has generated excitement, further observation and analysis are required to confirm its identity and determine whether it aligns with the predicted characteristics of Planet Nine.

Space The best candidate yet for the elusive Planet Nine has been spotted in two deep infrared surveys taken 23 years apart. If this mystery object really is Planet Nine, it would have a mass greater than Neptune, and currently be about 700 times farther from the sun than Earth is. Informative

Key Details & Data Points

  • What: A potential candidate for Planet Nine has been identified through analysis of archival infrared data from the IRAS and AKARI satellites. The candidate exhibits movement consistent with a distant planet.
  • Who: Terry Long Phan of National Tsing Hua University in Taiwan led the research team. Michael Brown and Konstantin Batygin of Caltech first proposed Planet Nine in 2016.
  • When: The IRAS data was collected in 1983, and the AKARI data was collected between 2006 and 2011. The research team's findings were posted to arXiv on April 24 and have been accepted for publication in the journal Publications of the Astronomical Society of Australia.
  • Where: The candidate is located in the outer reaches of the solar system, far beyond Neptune.

Key Statistics:

  • Distance: The candidate's orbit could range from 280 to 1,120 AU from the Sun (TechSpot).
  • Mass: The candidate is estimated to be more massive than Neptune (Space).
  • Movement: The object shifted approximately 47.4 arcminutes in AKARI's 2006 data from its position in IRAS's 1983 images (TechSpot).

Analysis & Context

The identification of a potential Planet Nine candidate represents a significant step in the ongoing search for this hypothesized planet. The analysis of archival infrared data provides a novel approach to detecting distant objects in the solar system. However, the discovery remains tentative, and further observations are needed to confirm the candidate's identity and orbit. The skepticism expressed by some astronomers highlights the challenges and uncertainties associated with detecting objects at such extreme distances. The upcoming launch of new telescopes and observatories could provide crucial data for resolving the Planet Nine debate.

Conclusion

The identification of a potential Planet Nine candidate has reignited the debate surrounding the existence of a ninth planet in our solar system. While the archival infrared data provides intriguing evidence, further observations and analysis are essential to confirm the candidate's identity and orbit. The upcoming launch of new telescopes and observatories holds promise for resolving this long-standing mystery and providing a more complete understanding of the outer solar system.
