3752 Camillo is an inclined contact-binary asteroid, classified as near-Earth object of the Apollo group, approximately 2.3 kilometers (1.4 miles) in diameter.It was discovered on 15 August 1985, by astronomers Eleanor Helin and Maria Barucci using a 0.9-metre (35 in) telescope at the CERGA Observatory in Caussols, France.
On February 16, 2019, React 16.8 was released to the public, introducing React Hooks. [18] Hooks are functions that let developers "hook into" React state and lifecycle features from function components. [19]
It was studied by radar at the Goldstone and Arecibo observatories from March 3 to 7, 2001. [5] The studies showed that the asteroid has a mean diameter of 1.1 km, assuming that 1950 DA is a retrograde rotator. [18] Optical lightcurve analysis by Lenka Šarounová and Petr Pravec shows that its rotation period is 2.1216 ± 0.0001 hours.
To be in the habitable zone, a planet around Alpha Centauri A would have an orbital radius of between about 1.2 and 2.1 AU so as to have similar planetary temperatures and conditions for liquid water to exist. [132] For the slightly less luminous and cooler α Centauri B, the habitable zone is between about 0.7 and 1.2 AU. [132]
Proxima Centauri b is the closest exoplanet to Earth, [19] at a distance of about 4.2 ly (1.3 parsecs). [4] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [20] As of 2021, it is unclear whether it has an eccentricity [e] [23] but Proxima Centauri b is unlikely to have any obliquity. [24]
The mirror has a polished area of 26.3 m 2 (283 sq ft), of which 0.9 m 2 (9.7 sq ft) is obscured by the secondary support struts, [16] giving a total collecting area of 25.4 m 2 (273 sq ft). This is over six times larger than the collecting area of Hubble's 2.4 m (7.9 ft) diameter mirror, which has a collecting area of 4.0 m 2 (43 sq
2.31 ± 0.03 (integral), [11] 2.41 ± 0.05 [16 Orcus ( minor-planet designation : 90482 Orcus ) is a dwarf planet located in the Kuiper belt , with one large moon, Vanth . [ 7 ] It has an estimated diameter of 870 to 960 km (540 to 600 mi), comparable to the Inner Solar System dwarf planet Ceres .
Prior to impact, 2023 CX 1 was on an Apollo-type orbit that crossed the orbits of Earth and Mars. [3] It orbited the Sun at an average distance of 1.63 astronomical units (244 × 10 ^ 6 km; 152 × 10 ^ 6 mi), varying from 0.92 AU at perihelion to 2.34 AU at aphelion due to its eccentric orbit. [3]
