Seventh Shooting Star Ever Spotted Before Impact For the seventh time, a small asteroid – a meteoroid as astronomers call it – was discovered in space as it raced towards Earth for impact. The predicted time and location of the impact (02:50 - 03:03 UTC, above northern France) were made possible wi

About 40 minutes later, follow-up observations reported by the Višnjan Observatory in Croatia confirmed the object. At this point, various impact assessment systems around the globe calculated a 100% impact probability, expected above the English Channel between 02:00 – 04:00 UTC. The asteroid was estimated to be around one meter in diameter and posed no threat to people or property.

Over the next seven hours, astronomers around the globe observed the Earth-bound object and pinpointed its ‘impact corridor’ over the Channel with a trajectory going from west to east. The object continued to be observed until just ten minutes before impact, only five minutes before it fell into Earth’s shadow becoming ‘invisible’.

First impact corridor reported by ESA’s tool Meerkat as reported at 21:33 UTC, with the actual impact time at 02:59 UTC in the middle of the uncertainty window. Credit: ESA / PDO

An Earth-sized Planet around an M5 Dwarf Star at 22 pcAn Earth-sized Planet around an M5 Dwarf Star at 22 pcWe report on the discovery of an Earth-sized transiting planet ($R_p=1.015\pm0.051\,R_\oplus$) in a $P=4.02$ day orbit around K2-415 (EPIC 211414619), an M5V star at 22 pc. The planet candidate was first identified by analyzing the light curve data by the K2 mission, and is here shown to exist in the most recent data from TESS. Combining the light curves with the data secured by our follow-up observations including high-resolution imaging and near infrared spectroscopy with IRD, we rule out false positive scenarios, finding a low false positive probability of $2\times 10^{-4}$. Based on IRD's radial velocities of K2-415, which were sparsely taken over three years, we obtain the planet mass of $3.0\pm 2.7\,M_\oplus$ ($M_p|7.5\,M_\oplus$ at $95\,\%$ confidence) for K2-415b. Being one of the lowest mass stars ($\approx 0.16\,M_\odot$) known to host an Earth-sized transiting planet, K2-415 will be an interesting target for further follow-up observations, including additional radial velocity monitoring and transit spectroscopy.
