IntroductionAsteroid (594913) 'Aylo'chaxnim, formerly designated as 2020 AV2, is the only one known to orbit inside Venus orbit. It was first observed by the Zwicky Transient Facility on January 4, 2020 (Bolin et al. 2020) and it may represent the largest member of a new population of small bodies with the aphelion distance smaller than 0.718 a.u

Introduction. The NEO Rapid Observation, Characterization and Key Simulations (NEOROCKS) project is funded (2020-2023) through the H2020 European Commission programme to improve our knowledge on near-Earth objects by connecting expertise in performing small body astronomical observations and the related modelling needed to derive their dynamical

We report the light-curve analysis for the event MOA-2020-BLG-135, which leads to the discovery of a new Neptune-class planet, MOA-2020-BLG-135Lb. With a derived mass ratio of $q={1.52}_{-0.31}^{+0.39}\times {10}^{-4}$ and separation s ≍ 1, the planet lies exactly at the break and likely peak of the exoplanet mass-ratio function derived by the

We report on the observations, analysis and interpretation of the microlensing event MOA-2019-BLG-008. The observed anomaly in the photometric light curve is best described through a binary lens model. In this model, the source did not cross caustics and no finite-source effects were observed. Therefore, the angular Einstein ring radius θ E cannot

Near-Earth objects (NEOs) deserve our attention because they pose an impact risk for Earth. A good example is the Chicxulub impactor that produced the Cretaceous/Tertiary mass extinction event 65 Myr ago (Bottke et al. 2007). Up to now, more than 1 milion of asteroids have been discovered, and about 28,700 are cataloged as NEOs. This number
