Definition: Having a wavy or cloud-like edge, often used to describe shapes or designs that resemble clouds.

Example: The artist used a nebuly pattern to create a dreamy effect in the painting.

Definition: Not related to astronomy or celestial bodies.

Example: The costs of the project were nonastronomical, making it feasible for the community.

Definition: Referring to matter that does not include baryons, which are particles like protons and neutrons that make up atomic nuclei.

Example: Dark matter is often considered to be nonbaryonic because it does not consist of ordinary atoms.

Definition: A type of star that becomes very bright for a short time and then slowly dims back to its normal brightness over weeks or years.

Example: Astronomers observed a nova that lit up the night sky for several weeks before fading away.

Definition: To move around a central point in a curved path, like a planet around a star.

Example: The Earth orbits the Sun once a year.

Definition: The path that an object takes as it moves around another object in space, like how the Earth moves around the Sun.

Example: The satellite is in a stable orbit around the planet.

Definition: To move or travel in a curved path around a central object, like a planet or star.

Example: The spacecraft will orbit the planet for several months before returning to Earth.

Definition: Relating to the path that an object takes as it moves around another object in space.

Example: The satellite is in an orbital path around the Earth.

Definition: A specific area around an atom's nucleus where electrons are likely to be found.

Example: Electrons occupy different orbitals depending on their energy levels.

Definition: A spacecraft that travels around a planet or moon without landing on it.

Example: The orbiter sent back stunning images of the planet's surface.

Definition: A device that represents the solar system, showing how the planets move around the sun using mechanical parts.

Example: The museum had a beautiful orrery that demonstrated the movements of the planets.

Definition: Relating to the apparent shift in position of an object when viewed from different angles.

Example: The parallactic shift of the stars can be observed from different points in Earth's orbit.

Definition: A unit of distance used in astronomy, equal to about 3.26 light-years, which is based on the apparent shift of stars as seen from different positions in Earth's orbit.

Example: The nearest star to Earth is about 4.24 parsecs away.
