Lists of trans-Neptunian objects 1970-01-01
Trans-Neptunian objects (TNOs) are celestial bodies located in the region of the Solar System beyond the orbit of Neptune. These objects are primarily found in a region known as the Kuiper Belt, though some are in scattered disc orbits, and others can be found in the Oort Cloud. TNOs include a variety of object types, such as dwarf planets, large asteroids, and smaller icy bodies.
Lists of unnumbered minor planets 1970-01-01
Lists of unnumbered minor planets refer to catalogues or compilations of minor planets (also known as asteroids) that have been officially discovered and observed but have not yet been assigned a permanent number by the International Astronomical Union (IAU). In the context of celestial objects, minor planets are typically those that are smaller than planets and don't dominate their orbital zones.
List of Earth-crossing asteroids 1970-01-01
A list of Earth-crossing asteroids refers to a collection of asteroids whose orbits bring them into close proximity to Earth's orbit. These asteroids are classified as "near-Earth objects" (NEOs), and more specifically, some of them are categorized as "Atira" (no close approaches to Earth) or "Apollo" and "Aten" asteroids, which do cross Earth's orbit.
List of Jupiter-crossing minor planets 1970-01-01
A list of Jupiter-crossing minor planets includes those small celestial bodies, primarily asteroids, that have orbits that bring them into proximity with Jupiter's orbit, or that cross it. These bodies are part of a larger category of near-Earth objects and include various types of asteroids, such as the Apollo and Amor families. Jupiter-crossing asteroids are of particular interest because they can provide insights into the early solar system, planetary formation, and dynamics of celestial mechanics.
List of Mars-crossing minor planets 1970-01-01
Mars-crossing minor planets are asteroids that have orbits that can cross the orbit of Mars. This means that their paths around the Sun bring them into the vicinity of Mars' orbit. These asteroids can potentially be classified as part of the broader group of near-Earth objects (NEOs) since their orbits may bring them close to Earth as well.
List of Mercury-crossing minor planets 1970-01-01
The List of Mercury-crossing minor planets consists of minor planets (or asteroids) whose orbits cross the orbit of Mercury, the innermost planet of our solar system. These objects are categorized based on their proximity to the Sun and their orbital characteristics. Mercury-crossing asteroids are of particular interest to astronomers because they can provide insights into the dynamic processes of the inner solar system.
List of Neptune-crossing minor planets 1970-01-01
The list of Neptune-crossing minor planets includes those asteroids and other small celestial bodies whose orbits intersect the orbit of Neptune. These objects are categorized as "Neptune-crossers" due to their potential for close encounters with Neptune's orbit. Such minor planets can have diverse physical characteristics and orbital elements. Some notable Neptune-crossing minor planets may include: 1. **2060 Chiron** - One of the largest centaurs, known for its cometary activity.
List of Saturn-crossing minor planets 1970-01-01
The term "Saturn-crossing minor planets" refers to a subset of minor planets (asteroids and other small bodies) that have orbits that cross the orbit of Saturn. These objects can belong to different groups, including asteroids from the main asteroid belt as well as centaurs and trans-Neptunian objects. The significance of these objects lies in their potential to cross the orbits of outer planets, which can affect their trajectories due to gravitational interactions.
List of Uranus-crossing minor planets 1970-01-01
List of Venus-crossing minor planets 1970-01-01
The list of Venus-crossing minor planets includes a group of small celestial bodies whose orbits bring them close to the orbit of Venus. These minor planets are typically asteroids, and their classifications are based on the paths they take around the Sun, specifically those that intersect with Venus's orbital path. A minor planet is considered a "Venus-crossing" object if it has a semimajor axis and eccentricity that allows its orbit to intersect with that of Venus.
List of centaurs (small Solar System bodies) 1970-01-01
Centaurs are a class of small Solar System bodies that exhibit characteristics of both asteroids and comets. They are typically found between the orbits of Jupiter and Neptune, and they often have unstable orbits that make them distinct from other small Solar System bodies. The following is a list of notable centaurs: 1. **Chiron (2060 Chiron)** - The first and most famous centaur, discovered in 1977.
List of fast rotators (minor planets) 1970-01-01
The list of fast rotators among minor planets refers to celestial bodies, primarily asteroids, that have relatively short rotation periods, meaning they complete a full spin on their axis in a short amount of time. These fast rotators can have rotation periods of less than about 5 hours. Studying fast rotators is significant because their rapid spins can affect their shapes, sizes, and surface features due to the centripetal forces at play.
List of instrument-resolved minor planets 1970-01-01
The term "instrument-resolved minor planets" refers to minor planets (which include asteroids and some comets) that have been observed and studied using specific instruments that allow astronomers to resolve them as distinct bodies, rather than as point sources of light in the sky. Such observations can yield valuable information about the size, shape, rotation, and surface properties of these minor planets. These bodies are often studied with powerful telescopes equipped with adaptive optics, photometry, or radar.
List of minor planets 1970-01-01
The term "minor planets" commonly refers to celestial objects that orbit the Sun and are not classified as major planets or comets. This category primarily includes asteroids and a few other types of small solar system bodies. A "List of minor planets" typically includes: 1. **Asteroids**: These are the most common types of minor planets, primarily found in the asteroid belt between Mars and Jupiter. Some well-known examples include Ceres, Vesta, and Pallas.
The Wide-field Infrared Survey Explorer (WISE) spacecraft, launched in December 2009, was instrumental in discovering and cataloging small bodies in the solar system, including a significant number of minor planets (asteroids). The spacecraft scanned the entire sky in infrared wavelengths, which made it particularly effective at detecting objects that are faint and cold, such as asteroids.
List of slow rotators (minor planets) 1970-01-01
The term "slow rotators" in the context of minor planets refers to asteroids that have a long rotation period, meaning they take a significant amount of time—often more than 10 hours—to complete a full rotation on their axis. This characteristic can be influenced by various factors, including the object's size, shape, and internal structure.
