Homestead is a L5 meteorite fallen in 1875 in Iowa, United States.
On the evening of 12 February 1875 above Iowa a brilliant fireball was observed. About 100 meteorite fragments fell over a 18-square-mile (47 km2) snowy countryside area from Amana to Boltonville in Iowa County. The first found fragment, a stone weighing about 3.5 kilograms (7.7 lb), was discovered by Sarah Sherlock 3 kilometres (1.9 mi) south of Homestead. [2] The area was wooded and covered by snow, impeding recovery efforts. On 10 February a 40 centimetres (16 in) snowfall blanketed the ground, preventing the great majority of the fragments from being discovered until Spring. The 74 pounds (34 kg) main mass was found along with a 48 pounds (22 kg) fragment buried 2 feet (0.61 m) in the soil. [2]
As of December 2011, approximately 230 kilograms (510 lb) has been found.
It is a L5 type ordinary chondrite. It is also brecciated and veined.

Campo del Cielo refers to a group of iron meteorites and to the area in Argentina where they were found. The site straddles the provinces of Chaco and Santiago del Estero, 1,000 kilometers (620 mi) north-northwest of Buenos Aires, Argentina. It is half that distance, north-east, to Paraguay's capital, Asunción. The crater field covers 3 by 18.5 kilometres and contains at least 26 craters, the largest being 115 by 91 metres.
The Cape York meteorite, also known as the Innaanganeq meteorite, is one of the largest known iron meteorites, classified as a medium octahedrite in chemical group IIIAB. In addition to many small fragments, at least eight large fragments with a total mass of 58 tons have been recovered, the largest weighing 31 tonnes. The meteorite is loosely named after the where the largest fragment was found: 23 miles (37 km) east of Cape York, in Savissivik, Meteorite Island, Greenland.
The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to a group of meteorites rich in organic compounds. Due to its mass and the fact that it was an observed fall, the Murchison meteorite is one of the most studied of all meteorites.
The pallasites are a class of stony–iron meteorite.
The Paragould Meteorite at 41 inches (1,000 mm) by 24 inches (610 mm) by 16 inches (410 mm) and weighing 370 kilograms (820 lb) is the second largest witnessed meteorite fall ever recovered in North America and the largest stony meteorite chondrite. It fell to Earth at approximately 4:08 a.m. on February 17, 1930.
The Tagish Lake meteorite fell at 16:43 UTC on 18 January 2000 in the Tagish Lake area in northwestern British Columbia, Canada.
Mesosiderites are a class of stony–iron meteorites consisting of about equal parts of metallic nickel-iron and silicate. They are breccias with an irregular texture; silicates and metal occur often in lumps or pebbles as well as in fine-grained intergrowths. The silicate part contains olivine, pyroxenes, and Ca-rich feldspar and is similar in composition to eucrites and diogenites.
Adelie Land is a meteorite discovered on December 5, 1912, in Antarctica by Francis Howard Bickerton (1889-1954), a member of Sir Douglas Mawson's Australasian Antarctic Expedition. It was named after Adélie Land and it was the first meteorite found in Antarctica.
The Sylacauga meteorite fell on November 30, 1954, at 12:46 local time in Oak Grove, Alabama, near Sylacauga. It is commonly called the Hodges meteorite because a fragment of it struck Ann Elizabeth Fowler Hodges (1920–1972).
Pultusk is an H5 ordinary chondrite meteorite which fell on 30 January 1868 in Poland. The event has been known as the stony meteorite shower with the largest number of pieces yet recorded in history. Made up of rocky debris, it consists of pyroxene or olivine chondrules deployed in mass plagioclase, there being also kamacite.
Park Forest is an L5 chondrite meteorite that fell on 26 March 2003 in Illinois, United States.
Gao–Guenie is a H5 ordinary chondrite meteorite that fell on Burkina Faso, West Africa, on March 5, 1960. The fall was composed of many fragments and it is one of the largest observed meteorite showers in Africa to date.
CI chondrites, sometimes C1 chondrites, are a group of rare stony meteorites belonging to the carbonaceous chondrites. Samples have been discovered in France, Canada, India, and Tanzania. Compared to all the meteorites found so far, their chemical composition most closely resembles the elemental distribution in the sun's photosphere.
Neuschwanstein was an enstatite chondrite meteorite that fell to Earth on 6 April 2002 at 22:20:18 GMT near Neuschwanstein Castle, Bavaria, at the Germany–Austria border.
The Novato meteorite is an ordinary chondrite which entered the earth's atmosphere and broke up over Northern California at 19:44 Pacific Time on 17 October 2012. The fireball created sonic booms and fragmented. The meteoroid was about 35 centimeters (14 in) across.
The Dronino meteorite is a 40-kilogram (88 lb) iron meteorite that was found in the Ryazan Oblast of Russia in July 2000. It is classified as an ataxite.
Fifteen pieces of the Kainsaz meteorite were seen to fall near Kainsaz, Muslyumovo, Tatarstan in September 13, 1937. The largest weighed 102.5 kilograms (226 lb), the total weight was ~200 kilograms (440 lb). As of January 2013 pieces were on sale for ~US$100/g. Kainsaz is the only observed fall in Tatarstan.
Žemaitkiemis meteorite is an ordinary chondrite that fell near Žemaitkiemis, Lithuania at about 8:33 pm on 2 February 1933. Using the argon–argon dating method, scientists have calculated its age to be about 520 million years.
The Braunschweig meteorite is a 1.3 kilograms meteorite that hit Melverode, a suburb in Braunschweig, Germany, at around 2:05 AM on April 23, 2013. It hit the concrete pavement in front of the home of Erhard Seemann, breaking into hundreds of fragments on impact, the largest of which is 214 grams. The meteorite created a small impact crater in the concrete, with a diameter of 7 cm (2.8 in) and a depth of 3 cm (1.2 in).
Alais or Allais is the first carbonaceous chondrite meteorite identified. It fell near Alès in 1806 in multiple fragments which together weighed 6 kg, although only 0.26 kg (9.2 oz) remains. The meteorite contains a number of elements in similar proportions to the solar system in its primordial state. It also contains organic compounds and water. It has proved to be one of the most important meteorites discovered in France.
