Comets with no meaningful orbit are those which have been observed but do not have a well-defined or predictable trajectory due to factors such as insufficient observation time, perturbations by celestial bodies, or a lack of data to accurately calculate their orbits. While there may not be an official "list" specifically categorized as "comets with no meaningful orbit," astronomers often refer to comets that are poorly defined or have uncertain orbits.

The "List of numbered comets" refers to a catalog of comets that have been assigned unique numbers by the International Astronomical Union (IAU) once their orbits have been well established through multiple observations. This numbering system is similar to the one used for asteroids. Typically, the list includes the comet's name (often reflecting its discoverer), its designated number, and sometimes additional information such as its orbital characteristics, historical significance, or notable appearances.

A list of periodic comets consists of comets that have predictable orbits and return to the inner solar system at regular intervals. Unlike non-periodic comets, which may only be seen once or can take thousands or even millions of years to return, periodic comets have well-documented periods of return.

The term "small Solar System bodies" refers to a diverse group of celestial objects in our Solar System that are not classified as planets or moons. These include various types of objects like asteroids, comets, and other minor bodies. Here's a brief overview of the main categories of small Solar System bodies: 1. **Asteroids**: These are rocky bodies that primarily reside in the asteroid belt between Mars and Jupiter.

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.

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.

In the context of the Solar System, "tumblers" refer to small celestial bodies that have highly irregular shapes and are generally considered to be remnants from the early solar system. These objects can be found in asteroid belts, comets, and other regions populated by minor planets and small bodies.

The "List of unnumbered minor planets" refers to a catalog of minor planets (also known as asteroids) that have been detected and observed but have not yet been assigned a numerical designation by the International Astronomical Union (IAU). Minor planets typically receive a number once they are confirmed and their orbits are well-established.

The timeline of Iran's nuclear program is complex and spans several decades, involving various developments in technology, international diplomacy, and geopolitical tensions. Here’s a summarized timeline of key events in the Iranian nuclear program: ### 1950s-1970s: Early Development - **1957**: The U.S. and Iran establish the Atoms for Peace program, facilitating the development of nuclear technology in Iran.

Brokdorf is a small village in northern Germany, located in the state of Schleswig-Holstein. It is known for being home to the Brokdorf nuclear power plant, which was commissioned in the 1980s. The plant has been a point of controversy due to protests and debates over nuclear energy and safety. The power plant itself is a pressurized water reactor and has been operational since its opening, contributing to the local and national power grid.

Soviet anti-nuclear activists were individuals and groups in the Soviet Union who opposed nuclear weapons and nuclear power during the Cold War and beyond. Their activism emerged in response to the dangers posed by nuclear arms races, the potential for nuclear war, and the environmental and health impacts of nuclear power plants and weapons testing.

English anti-nuclear weapons activists are individuals and groups in England who advocate against the development, proliferation, and use of nuclear weapons. This movement has its roots in the broader global anti-nuclear movement that gained significant momentum during the Cold War, particularly in the 1950s and 1980s. These activists typically focus on various issues, including: 1. **Disarmament**: Advocating for the dismantling of nuclear arsenals and promoting treaties aimed at reducing or eliminating nuclear weapons.

"Stop the City" was a series of protests that took place in London on October 15, 1983. Organized primarily by anti-nuclear and anti-capitalist activists, particularly the Stop the City Collective, the protests aimed to disrupt the workings of the financial district in London, which they viewed as a center of capitalist and militaristic power.

Faslane Peace Camp is a permanent peace camp located near the Faslane Naval Base in Scotland, which is home to the UK's nuclear submarine fleet. Established in 1982, the camp was created as a protest against the presence and activities of nuclear weapons in the area, particularly in response to Cold War tensions and the deployment of Trident submarines. The Peace Camp is run by activists who seek to raise awareness about nuclear disarmament and promote peaceful alternatives to military action.

The nuclear history of the United Kingdom is a complex narrative involving scientific research, military strategy, and energy production. Here’s an overview of the key milestones: ### Early Developments (1930s-1940s) - **1930s**: Early research on nuclear physics began in the UK, with scientists like James Chadwick discovering the neutron in 1932.

Nuclear power in Bulgaria is primarily generated from the Kozloduy Nuclear Power Plant, which is the country's sole nuclear facility. It has played a crucial role in Bulgaria’s energy landscape since its first reactor was commissioned in the 1970s.

Nuclear power in Germany has been a significant part of the country's energy landscape, particularly from the 1970s until the early 2000s. However, the role of nuclear energy in Germany has been shaped by a combination of political decisions, public opinion, and safety concerns, particularly in the aftermath of the 2011 Fukushima disaster in Japan.

Nuclear power in Pakistan refers to the use of nuclear energy for electricity generation and other applications in the country. Pakistan's nuclear program began in the 1950s, but it gained significant momentum in the 1970s and 1980s, leading to the development of both nuclear weapons and civilian nuclear power generation capabilities.
