গতি Dynamics of binary asteroids (379) Huena

The study of asteroid satellites is a relatively young science compared to planetary satellites. The movement of these satellites is mainly controlled by the gravitational field generated by the major asteroids. For the first time, scientists have detected a faint disturbance in a movement Satellite (Satellite may specify 🙂 OfAsteroids (An asteroid is a celestial object whose dimensions vary by a few tens …) By a body outside the asteroid system: The sun (The Sun (Sol in Latin, Helios or Ήλιος in Greek) is the star …).

(2011, Icarus, 212) reported a discrepancy between the predicted position and the observation. Then, three French researchers compiled all available images of the system, which were obtained with the help of a large terrestrial telescope. The camera (The word camera comes from Latin: chamber, for photographic chamber. It nominates a device …) Per Adaptive optics (Adaptive optics is a technique that makes it possible to correct distortion in real time …). Based on these 40 observations over 11 years, they concluded in a new study that,Orbit (In celestial mechanics, an orbit is a body-drawn trajectory in space …) The satellite is strongly influenced by the gravitational effect of the sun, as opposed to what is observed on large asteroid satellites in the main belt. The satellite is spinning Nearby (Auto is the name that gives Avian naming (update) in French …) About 3500 km from the asteroid, 80 Earths for a period of days. This distance is relatively long, and Mass (The term mass is used to determine two quantities connected by one …) Fairly pale asteroids. The Field (A field matches the concept of defined space 🙂 Of Gravity (Gravity is one of the four basic interactions in physics.) The asteroid that is formed in the case of its satellites is actually weak and allows the sun to work on the motion of the satellite.

Gravity is a law that depends on the distance between objects. When a satellite is closer to the Sun than it orbits an asteroid, it feels the Sun’s gravity more than the asteroid. Conversely, when it is away from the sun, the asteroid suffers a little more consequences. 11 year resultsObservation (Observation is the act of carefully following events, without wanting to see them …) Confirm the effect of the sun in the orbit of the satellite. These are all known asteroids Day (Day or day is the break that separates sunrise from sunset; it is …)Another major-belt asteroid, (3749) Balam, may exhibit this same feature.
