Astronomer: A scientist specializing in the study of celestial bodies, space, and physical universes.
Chaos: A state of confusion and disorder.
Computer Model: A software application that simulates a real function, phenomenon, or event on a computer.
Universe: A term that refers to the cosmos and everything within it.
Disk: Flat, round objects that are typically thin. (In astronomy) planets can form from a rotating collection of gas and dust, or it can describe the structure of a large rotating body, such as a spiral galaxy.
I’ll eject it: The act of forcefully removing or discarding something from its place or container.
Gravity: The attractive force that pulls objects with mass toward one another, with larger masses exerting a stronger gravitational pull.
Jupiter: The largest planet in the solar system, with a day lasting 9 hours and 55 minutes. As a gas giant with low density, it primarily consists of hydrogen and helium, and it emits more heat than it receives from the Sun due to the compression of its mass.
Mars: The fourth planet from the Sun, situated one planet away from Earth. It has seasons and atmospheric humidity, but is about half the diameter of Earth.
Mercury: (In astronomy, this term is capitalized) The planet closest to the Sun, named after the Roman god (Mercury), with a year lasting only 88 Earth days.
Model: A simulation of real events (usually created with computer software) designed to predict outcomes or demonstrate how something functions.
Orbit: The curved path that a celestial object or spacecraft follows around a star, planet, moon, or galaxy, completing one full circuit around the body.
Pluto: A distant body found in the Kuiper Belt, beyond Neptune. Recognized as a dwarf planet, it is the ninth largest object in orbit around the Sun.
Risk: The potential for adverse outcomes or mathematical possibility; for instance, exposure to radiation poses a cancer risk. It can also refer to danger itself (e.g., Among the cancer risks people faced were radiation and arsenic contamination in drinking water).
Solar System: The Sun and all celestial bodies that orbit it, including planets, moons, asteroids, meteors, and comets.
Stars: The fundamental components from which galaxies are formed. Stars arise when gravity compresses clouds of gas, and upon reaching sufficient temperatures, they emit light and various forms of electromagnetic radiation. The Sun is our closest star.
Solar: Pertaining to the Sun at the center of the solar system, located about 27,000 light-years from the Milky Way’s center. It also refers to stars similar to our Sun.
Venus: The second planet from the Sun, featuring an iron core, rocky mantle, and crust, much like Earth. Venus lost much of its water a long time ago, as ultraviolet rays destroyed the water molecules and allowed hydrogen atoms to escape into space. Volcanoes on its surface release high levels of carbon dioxide, which have built up in its atmosphere. Consequently, the air pressure on Venus is 93 times greater than that on Earth, maintaining surface temperatures around a scorching 460° Celsius (860° F).
