This ordinary chondriteWork in Progress Ordinary chondrites (OCs) are the largest meteorite clan, comprising approximately 87% of the global collection and 78% of all falls (Meteoritical Society database 2018)1. Meteorites & the Early Solar System: page 581 section 6.1 OC of type 5 or 6 with an apparent shock stage of S1, Click on Term to Read More weighing 41.8 kg (92 pounds) is only one of five meteorites found in Florida, all of them stony. Details published in the Naples Daily News for July 4, 1993 describe the events of the day in 1938 or 1939 when Reginald Lyles went digging in a local Indian sand mound that measured 300 feet in diameter and 6 feet high, located between Bonita Beach Road and the Imperial River about halfway between U.S. 41 and the beach. While searching for relics, he found the large rock situated amid several skeletons. It was not until 1956, after having spent many years lying outside under a mango tree, that the meteoriteWork in progress. A solid natural object reaching a planet’s surface from interplanetary space. Solid portion of a meteoroid that survives its fall to Earth, or some other body. Meteorites are classified as stony meteorites, iron meteorites, and stony-iron meteorites. These groups are further divided according to their mineralogy and Click on Term to Read More was brought to the attention of the Smithsonian and a sample sent in for authentication. The meteorite was subsequently purchased by the Meteorite Curator for the Smithsonian, Dr. Edward Henderson, for the sum of $200, and samples have been distributed through the years to many other institutions including those in New York, Chicago, Boston, Australia, and Russia.
Although the S(IV)-type asteroid 6 Hebe has been considered as a probable candidate for the
parent bodyThe body from which a meteorite or meteoroid was derived prior to its ejection. Some parent bodies were destroyed early in the formation of our Solar System, while others like the asteroid 4-Vesta and Mars are still observable today. Click on Term to Read More of the H-type ordinary
chondritesChondrites are the most common meteorites accounting for ~84% of falls. Chondrites are comprised mostly of Fe- and Mg-bearing silicate minerals (found in both chondrules and fine grained matrix), reduced Fe/Ni metal (found in various states like large blebs, small grains and/or even chondrule rims), and various refractory inclusions (such Click on Term to Read More, hydrocode models show inconsistencies exist between expected and observed CRE ages based on the scenario of direct injection into resonances. The steady delivery of
H chondriteOrdinary chondrites with a high content of free Ni-Fe metal (15-19 vol. %) and attracted easily to a magnet. Their main minerals are olivine (Fa16-20) and the orthopyroxene bronzite (Fs14.5-18.5), earning them their older name of bronzite chondrites. Chondrules average ~0.3 mm in diameter. Comparison of the reflectance spectra of Click on Term to Read More material from 6 Hebe to Earth also remains unexplained. Current studies by Rubin and Bottke (2009) have led to the conclusion that family-forming events resulting in large
meteoroidSmall rocky or metallic object in orbit around the Sun (or another star). reservoirs, which have homogenous compositions and locations near dynamical resonances such as the Jupiter 3:1 mean motion resonance, are the likely source of the most prevalent falls including H chondrites and HED achondrites (especially howardites). As a matter of fact, a number of asteroids having H-like mineralogies have been observed near the 3:1 (2.50
AUThe astronomical unit for length is described as the "mean" distance (average of aphelion and perihelion distances) between the Earth and the Sun. Though most references state the value for 1 AU to be approximately 150 million kilometers, the currently accepted precise value for the AU is 149,597,870.66 km.

Due in part to the intense temperature and moisture conditions in the state of Florida, only four meteorites have been found there to date, in addition to two recovered falls. Besides Bonita Springs, approximately 1 kg of L4 fragments were brought up in a net offshore of Lake
Okechobee, a 502 g, H4 stone was plowed up in
Eustis, and a 10.9 kg H5 stone was found near
Grayton Beach. In 2004, November 8 at 6:15 P.M., Orlando resident Donna Shuford heard a meteorite bounce off her car and hit the side of her house. Fragments composing an ~180 g
eucriteMost common type of achondrite meteorite and a member of the HED group. Eucrites are basalts composed primarily of pigeonite and anorthite (An60-98). Eucrites have been placed into three subgroups based on mineralogical and chemical differences. • Non-cumulate eucrites represent the upper crust that solidified on a magma ocean after Click on Term to Read More were recovered. In 2016, January 24 at 10:27 A.M., numerous eyewitnesses observed a bright
fireballA fireball is another term for a very bright meteor, generally brighter than magnitude -4, which is about the same magnitude of the planet Venus as seen in the morning or evening sky. A bolide is a special type of fireball which explodes in a bright terminal flash at its end, often with visible fragmentation.
