The dynamically hazardous asteroid 2025 TV10: A new co-orbital asteroid of Venus V. Carruba, R. Sfair, O. C. Winter Astronomy and Astrophysics, 2026 Context. Twenty co-orbital asteroids of Venus are currently known, several of which may evolve into potentially hazardous asteroids (PHAs) over timescales of thousands of years. Aims. We report the identification and first dynamical characterization of 2025 TV 10 , a newly discovered Venus co-orbital asteroid, and assess its potential collisional hazard to Earth. Methods. We performed numerical simulations of a large number of asteroid clones, and we studied their close encounters with Venus and Earth. Results. The asteroid may leave its co-orbital configuration on timescales of 1200 yr. The orbit of 2025 TV 10 is one of the closest of the absolute minimum of the “minimum orbital intersection distance” (MOID) with Earth for the Venus co-orbital asteroids known to date. Conclusions. Owing to its orbital parameters, 2025 TV 10 represents one of the most dynamically hazardous members of the Venus co-orbital population identified to date. Its faint magnitude and restricted observability windows make future observations challenging but essential for constraining its orbit.
The PLATO mission Heike Rauer, Conny Aerts, Juan Cabrera, Magali Deleuil, Anders Erikson, et al. Experimental Astronomy, 2025 PLATO (PLAnetary Transits and Oscillations of stars) is ESA’s M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to <2R $$_\\textrm{Earth}$$ Earth ) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations from the ground, planets will be characterised for their radius, mass, and age with high accuracy (5%, 10%, 10% for an Earth-Sun combination respectively). PLATO will provide us with a large-scale catalogue of well-characterised small planets up to intermediate orbital periods, relevant for a meaningful comparison to planet formation theories and to better understand planet evolution. It will make possible comparative exoplanetology to place our Solar System planets in a broader context. In parallel, PLATO will study (host) stars using asteroseismology, allowing us to determine the stellar properties with high accuracy, substantially enhancing our knowledge of stellar structure and evolution. The payload instrument consists of 26 cameras with 12cm aperture each. For at least four years, the mission will perform high-precision photometric measurements. Here we review the science objectives, present PLATO‘s target samples and fields, provide an overview of expected core science performance as well as a description of the instrument and the mission profile towards the end of the serial production of the flight cameras. PLATO is scheduled for a launch date end 2026. This overview therefore provides a summary of the mission to the community in preparation of the upcoming operational phases.
