A list of minor planets named after places includes celestial bodies (typically asteroids) that are named in honor of geographical locations, regions, cities, and other significant landmarks. These names often reflect cultural, historical, or personal significance associated with the area being honored. While I can't provide an exhaustive list, here are some notable examples: 1. **243 Ida** - Named after the mountain Ida on the Greek island of Crete.

The list of named minor planets from 250,000 to 299,999 is quite extensive, and it's continuously updated as new minor planets are discovered and named. For detailed information about each minor planet's name, designation, and other relevant data, it is best to refer to resources like the International Astronomical Union (IAU) or specific databases such as the JPL Small-Body Database.

The list of named minor planets ranging from 30,000 to 39,999 includes astronomical objects that have been given specific names. These names can be based on a variety of themes, including mythology, notable individuals, or other culturally significant concepts. The minor planets in this range are typically numbered and named by the International Astronomical Union (IAU) after their discovery.

The list of named minor planets numbered from 60000 to 69999 includes various small celestial bodies that have been discovered and officially named. Each name is typically chosen to honor notable individuals, places, myths, or other entities. Here’s a brief overview of some named minor planets in that range: - **60000**: 60000 Ptolemaios - Named after the ancient Greek astronomer Claudius Ptolemy.

The "List of named minor planets: A" is a compilation of minor planets (also known as asteroids) that have been given designated names. This list is part of a larger catalog maintained by the International Astronomical Union (IAU), which officially assigns names to celestial bodies. Minor planets are typically given names that are significant to the discoverer, mythology, geography, or science.

The "List of named minor planets" for those starting with the letter "H" includes minor planets (or asteroids) that have been formally named. These named minor planets can include a variety of interesting objects from the asteroid belt, Kuiper belt, and other regions of the solar system.

The "List of named minor planets: K" refers to a catalog of minor planets (also known as asteroids) that have been given specific names starting with the letter "K." These minor planets are celestial bodies that orbit the Sun and are not classified as planets or comets.

The list of named minor planets (also known as asteroids) beginning with the letter "S" includes numerous objects that have been officially named by the International Astronomical Union (IAU). This includes asteroids ranging from well-known ones, like 1 Ceres, to many others that might be less recognized.

Isonoe is one of the moons of Jupiter. It is classified as a non-regular or irregular moon, meaning that it has an eccentric and inclined orbit compared to the planet's equatorial plane. Isonoe was discovered in 2000 and is part of a group of moons known as the Himalia group, named after the largest moon in that cluster, Himalia. Isonoe has a diameter of about 2 kilometers (1.

The "List of named minor planets: X" refers to a compilation of minor planets (or asteroids) that have been designated with names that start with the letter "X." Minor planets are small celestial bodies that orbit the Sun, and many of them are named after various figures from mythology, history, literature, and other cultural references.

The list of minor planets between 10,001 and 11,000 includes various asteroids that have been assigned numbers by the Minor Planet Center (MPC). Each minor planet is typically named after a person, place, or concept. The names often honor individuals or reflect historical or cultural significance.

Tin pest, also known as "tin disease" or "tin decay," is a phenomenon that affects tin, particularly at low temperatures (below approximately 13.2 °C or 55.8 °F). It involves the transformation of beta-tin (the stable form of tin at higher temperatures) into alpha-tin, which is a powdery, non-metallic form of tin that can lead to the deterioration of tin objects.

The list of minor planets from 103001 to 104000 refers to a collection of small celestial bodies that orbit the Sun, primarily in the asteroid belt. These minor planets, also known as asteroids, are numbered sequentially starting from 1. Each minor planet is assigned a unique number upon discovery, and many also have specific names given by the discoverers.

The list of minor planets numbered from 111001 to 112000 includes a variety of celestial objects discovered and cataloged by astronomers. Each minor planet is assigned a unique number by the International Astronomical Union (IAU) once it has been observed and confirmed. This list can include asteroids from the main asteroid belt, near-Earth objects, and other small bodies in our solar system.

The list of minor planets from 116001 to 117000 includes a range of asteroids that have been discovered and cataloged. Each entry typically includes information such as the minor planet's provisional designation, its number, and sometimes its name if it has been officially assigned one.

Euporie is one of the moons of Jupiter. It is classified as a member of the Himalia group, a cluster of irregular moons that share similar orbits and characteristics. Euporie was discovered in 2003 and is notable for its relatively small size, with a diameter of about 2 kilometers (approximately 1.2 miles).

The "List of minor planets: 121001–122000" refers to a set of minor planets (also known as asteroids) that have been identified and numbered by the Minor Planet Center (MPC). Each minor planet is given a unique number and often a name, and these numbers are assigned in the order of discovery. This specific range includes minor planets numbered from 121001 to 122000.

The List of minor planets from 125001 to 126000 is a compilation of numbered asteroids and minor planets that have been cataloged by the International Astronomical Union (IAU). Each minor planet is assigned a unique number and often has a name that is either descriptive or honors a person, place, or cultural theme.

Europa is one of Jupiter's largest moons and is the sixth-largest moon in the solar system. It was discovered in 1610 by the Italian astronomer Galileo Galilei and is one of the four largest moons of Jupiter, known as the Galilean moons, which also include Io, Ganymede, and Callisto. Europa is especially notable for several reasons: 1. **Icy Surface**: Europa has a smooth, icy surface that is believed to be mainly composed of water ice.
