Meaning and Definition
A coordinate in a galactic coordinate system, measured in degrees north or south from the galactic plane (analogous to latitude on Earth).
In astronomy, the angular distance of a celestial object from the plane of the Milky Way Galaxy. It is part of a coordinate system centred on our galaxy, used to map the positions of stars and other objects relative to the galactic disc.

Common Mistakes When Using “galactic latitude”
- Confusing it with 'declination' (which is measured from the celestial equator).
- Using it without its paired coordinate 'galactic longitude'.
- Capitalising it incorrectly (not a proper noun).
- Attempting to use it in non-astronomical contexts.
FAQ
Frequently Asked Questions
No, they are analogous concepts but use different reference planes. Earth's latitude is measured from the equator, while galactic latitude is measured from the galactic plane (the mid-plane of the Milky Way).
It ranges from -90° (south galactic pole) through 0° (on the galactic plane) to +90° (north galactic pole).
It helps astronomers avoid the dense gas and dust in the galactic plane, which obscures visible light. Observations at high galactic latitudes offer clearer views of distant galaxies and the cosmic microwave background.
No. It is a highly specialised scientific term. General English learners will almost certainly never encounter it unless they study astronomy.
A coordinate in a galactic coordinate system, measured in degrees north or south from the galactic plane (analogous to latitude on Earth).
Galactic latitude is usually formal, technical, academic in register.
Galactic latitude: in British English it is pronounced /ɡəˈlæk.tɪk ˈlæt.ɪ.tjuːd/, and in American English it is pronounced /ɡəˈlæk.tɪk ˈlæt.ə.tuːd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of the Milky Way as a giant plate. 'Galactic latitude' tells you how far above or below that plate (the galactic plane) something is, just like Earth's latitude tells you how far north or south of the equator you are.
Conceptual Metaphor
THE GALAXY IS A SPHERE/CIRCLE (projecting the Earth's coordinate system onto the galaxy).
