(469219) Kamo`oalewa is a small near-Earth asteroid (NEA) that currently quasi-satellite of the Earth. Light curve measurements have also revealed rotation period only about 30 minutes. This has been selected as target Tianwen-2 sample-return mission China National Space Administration. The first goal this paper to observe and improve orbit determination Kamo`oalewa, better determine Yarkovsky effect acting on it. second estimate thermal inertia asteroid, using an improved determination.

Asteroid 2024 XA$_1$ was discovered on 3 December at 05:54 UTC by the Bok telescope in Kitt Peak, Arizona, and impacted Earth about 10 hours later over a remote area of Sakha Republic (Russia). The estimated size object one meter, atmospheric entry produced bright fireball that captured webcam several eyewitnesses. first impact alert issued 07:50 Meerkat Guard European Space Agency, which triggered subsequent follow-up observations confirmed both to be real occurrence with Earth. Here we...
Context. (469219) Kamo`oalewa is a small near-Earth asteroid, which currently quasi-satellite of the Earth. Lightcurve measurements also reveal rotation period only about 30 minutes.

Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speeds. Understanding their properties, including rotation state, is crucial for assessing risks and mitigation strategies. Traditional photometric methods face challenges in accurately collecting data fast-moving NEOs. Aims. This study introduces innovative approach to aperture photometry, tailored analyzing trailed images of Our primary aim extract state information fast rotators. Methods. We applied...
Context . The measurement of the Yarkovsky effect on near-Earth asteroids (NEAs) is common practice in orbit determination today, and number detections will increase with developments new more accurate telescopic surveys. However, process finding identifying spurious ones not yet automated, it often relies personal judgment. Aims We aim to introduce a automated procedure that can search for NEA candidates measure effect, identify detections. Methods expected semi-major axis drift an caused...
Abstract We describe results of a planetary defense exercise conducted during the close approach to Earth by near-Earth asteroid (99942) Apophis 2020 December–2021 March. The community has been conducting observational campaigns since 2017 test operational readiness global capabilities. These community-led exercises were carried out with support NASA’s Planetary Defense Coordination Office and International Asteroid Warning Network. campaign is third in our series exercises. goal this was...
Photometric measurements allow the determination of an asteroid's absolute magnitude, which often represents sole means to infer its size.Photometric observations can be obtained in a variety filters that unique specific observatory.Those are then calibrated into bands with respect reference star catalogs.In order combine all different for evaluation, photometric need converted common band, typically V-band.Current bandcorrection schemes use by IAU's Minor Planet Center (MPC), JPL's Near...

We present a concept for kinetic impactor demonstration mission, which intends to change the spin rate of previously-visited asteroid, in this case 25143 Itokawa. The mission would determine efficiency momentum transfer during an impact, and help mature technology required both are important precursors future space deflect asteroid by collisional means emergency situation. Most concepts date based on changing asteroid's heliocentric orbit require reconnaissance spacecraft measure very small...
Abstract Deflection missions to near-Earth asteroids will encounter non-negligible uncertainties in the physical and orbital parameters of target object. In order reliably assess future impact threat mitigation operations such have be quantified incorporated into mission design. The implementation deflection demonstration offers great opportunity test our current understanding relevant their consequences, e.g., regarding kinetic impacts on asteroid surfaces. this contribution, we discuss...
As a consequence of the large (and growing) number near-Earth objects discovered, some them are lost before their orbit can be firmly established to ensure long-term recovery. A fraction these present non-negligible chances impact with Earth. We method targeted observations that allowed us eliminate risk by obtaining deep images area where object would be, should it on collision orbit. 2006 QV89 was one objects, chance Earth 2019 September 9.

There are several differences between the planetary entry of space vehicles and that asteroids. In this work we do investigate applicability classical methods approaches developed for debris analysis to asteroid entry. particular, in-house DEBRIS tool, which has been designed address problem uncontrolled re-entry objects, is used here predict survivability ground footprint fragments. The results obtained Chelyabinsk event presented as test case. A comparison with current available...
ESA is currently studying three Planetary Defence related missions in the framework of Space Safety (S2P) Programme:- NEOMIR (Near Earth Mission Infra Red): A space based IR telescope to be stationed at Earth-Sun Lagrange point (L1), which will scanning inner solar system for Asteroids with elongations not readily accessible from groundbased observations.- RAMSES (Rapid Apophis SEcurity and Safety): Rendezvous mission asteroid (99942)Apophis (based on maximum re-use components Hera...
