# data[].attributes.body
The angular distance from horizon to object, measured along a vertical circle.

# data[].attributes.body
The accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, into an accretion disk.

# data[].attributes.body
The diameter of the lens or mirror in a telescope that collects light.

# data[].attributes.body
A unit of measurement equal to 149.6 million kilometers, the mean distance from the center of the earth to the center of the sun.

# data[].attributes.body
Frozen leftovers from the formation of the solar system composed of dust, rock, and ices.

# data[].attributes.body
A small, extremely bright region in the center of a galaxy that's powered by a supermassive black hole.

# data[].attributes.body
A small, rocky, irregularly shaped celestial body that orbits the Sun.

# data[].attributes.body
The horizontal angle measured clockwise from true north to the vertical circle passing through a celestial object.

# data[].attributes.body
A type of solar eclipse that occurs when the Moon passes between the Earth and the Sun, but doesn't completely cover the Sun.

# data[].attributes.body
A recognizable pattern or group of stars in the night sky, often forming a simple shape, which can be part of a constellation or even span across multiple constellations.

# data[].attributes.body
A layer of gases that surrounds a celestial body, such as a planet or star, and is held in place by the body's gravity.

# data[].attributes.body
Relating to the sky or heavens, or to the coordinate systems that represent the position of celestial bodies.

# data[].attributes.body
A group of stars that appear to form a pattern in the night sky.

# data[].attributes.body
An astronomical event that occurs when one celestial body passes into the shadow of another or is blocked by it.

# data[].attributes.body
A celestial body that meets the following:

It orbits the sun

It has enough mass to be roughly spherical in shape

It has enough gravitational attraction to clear the neighborhood around its orbit

# data[].attributes.body
A concentration of mass so dense that nothing not even light can escape its gravitational pull once swallowed up.

# data[].attributes.body
A vast collection of stars, gas, and dust, typically 10,000 to 100,000 light-years in diameter and containing billions of stars.

# data[].attributes.body
A supermassive black hole gorging on gas at the center of a distant galaxy.
