New object flying in our solar system? ASU explains
After the news broke, CVHP reached out to the ASU's Department of Physics & Geosciences to find out more information about the sednoid designated as 2023 KQ14.
What is a sednoid?
According to Kenneth Carrell, the Planetarium Director at ASU, the 'sednoid' designation is given to objects with some characteristics similar to a Neptunian object and a potential dwarf planet called Sedna. The International Astronomical Union (IAU) has specific definitions for a 'planet' and a 'dwarf planet' and there are currently only five officially recognized dwarf planets.
'Future observations may result in more objects getting moved into that category, including potentially Sedna,' said Carrell.
How 2023 KQ14 was found?
Carrell told the publication that the discovery of this object was made using the Subaru Telescope which located in Hawaii. This telescope has a diameter of just over 8 meters and is in the top 10 largest telescopes currently in use.
'Interestingly, although this object was 'discovered' recently by the team using the Subaru Telescope, they used archival images from surveys as far back as 2014 to get a better idea of the orbit of the object (they discuss these 'precoveries' in the Methods section of the Nature article),' said Carrell.
He then explained that there are surveys and telescopes being dedicated to discoveries like this, so discovering objects like 2023 KQ14 may be much more common in the near future.
'So, this object could have been discovered years ago if people knew where to look for it,' said Carrell.
More Facts about 2023 KQ14
Carrell said 2023 KQ14 is an object in our Solar System and described it as a Trans-Neptunian object on a highly elliptical orbit. A trans-Neptunian object is a celestial body that orbits the Sun at a greater average distance than Neptune.
He said 2023 KQ14's perihelion, or closest approach to the Sun, is almost 70 times farther from the Sun than Earth, and more than twice as far as Neptune, the most distant planet in our Solar System. In contrast, its aphelion, or farthest distance from the Sun, is more than 400 times the Earth-Sun distance, placing it well beyond the heliopause, the widely recognized boundary between the Solar System and interstellar space.
He also said that 2023 KQ14 is not possible to see with your unaided eye or with amateur telescopes. The apparent magnitude of the object is just over 25, which is more than 50 million times fainter than your eye can detect in the darkest of conditions. He also added that observing objects this faint requires the largest ground-based telescopes or space telescopes.

Canada Awards New Patent to bioAffinity Technologies for CyPath® Lung, Company's Noninvasive Lung Cancer Diagnostic
New patent protects market expansion to the north where lung cancer is leading cause of cancer deaths SAN ANTONIO, July 22, 2025--(BUSINESS WIRE)--bioAffinity Technologies, Inc. (Nasdaq: BIAF; BIAFW), a biotechnology company advancing early-stage cancer diagnostics including CyPath® Lung, the Company's commercially available test for early-stage lung cancer, today announced its patent related to a method to detect lung disease through flow cytometry analysis of sputum has been allowed by the Canadian Patent Office. This patent strengthens the international protection of the Company's diagnostic platform that powers its flagship test, CyPath® Lung. "As with the recent announcement of the award of our patent in China, this Canadian patent reflects our continued execution toward building long-term shareholder value through innovation, protection of our unique assets, and a clear focus on early cancer detection that can save lives," said Maria Zannes, President and CEO of bioAffinity Technologies. Lung cancer is the leading cause of cancer death in Canada, according to the Canadian Cancer Society. In 2024, approximately 31,000 Canadians were diagnosed with lung cancer, and approximately 20,700 people died of the disease. More than 70% of the lung cancer deaths were linked to smoking. "We believe that the award of this patent by the Canadian Patent Office further validates the diagnostic platform behind CyPath® Lung, expands the global footprint of our intellectual property portfolio and highlights the strength of our science," Ms. Zannes said. "Recent case studies highlight CyPath Lung's ability to detect lung cancer at its earliest stages, making our test all the more valuable in Canada where 50% of all lung cancer cases are diagnosed late at Stage IV with the five-year survival rate overall of about 19% in Canada, according to government statistics." The Canadian patent (Patent No. 3,136,245) – titled "System and Method for Determining Lung Health" – protects the use of defined antibodies and the porphyrin TCPP to label cell populations in sputum and the use of flow cytometry to determine the presence of lung cancer cells in the sputum. CyPath® Lung is the Company's first commercial product, with clinical study results demonstrating 92% sensitivity, 87% specificity and 88% accuracy in detecting lung cancer in patients at high risk for the disease who had small lung nodules less than 20 millimeters. About CyPath® Lung CyPath® Lung uses proprietary advanced flow cytometry and artificial intelligence (AI) to identify cell populations in patient sputum that indicate malignancy. Automated data analysis helps determine if cancer is present or if the patient is cancer-free. CyPath® Lung incorporates a fluorescent porphyrin that is preferentially taken up by cancer and cancer-related cells. Clinical study results demonstrated that CyPath® Lung had 92% sensitivity, 87% specificity and 88% accuracy in detecting lung cancer in patients at high risk for the disease who had small lung nodules less than 20 millimeters. Diagnosing and treating early-stage lung cancer can improve outcomes and increase patient survival. For more information, visit About bioAffinity Technologies, Inc. bioAffinity Technologies, Inc. addresses the need for noninvasive diagnosis of early-stage cancer and other diseases of the lung and broad-spectrum cancer treatments. The Company's first product, CyPath® Lung, is a noninvasive test that has shown high sensitivity, specificity and accuracy for the detection of early-stage lung cancer.

Moleculin Biotech, Inc. is a Phase 3 clinical stage pharmaceutical company advancing a pipeline of therapeutic candidates addressing hard-to-treat tumors and viruses. The Company's lead program, Annamycin, is a next-generation highly efficacious and well tolerated anthracycline designed to avoid multidrug resistance mechanisms and to lack the cardiotoxicity common with currently prescribed anthracyclines. Annamycin is currently in development for the treatment of relapsed or refractory acute myeloid leukemia (AML) and soft tissue sarcoma (STS) lung metastases.
