Moon Position Calculator


Calculate the approximated position of the moon in Earth-centered Inertial (ECI) frame for given time.

Note: UTC date (dd/mm/ or mm/dd) and time (12h or 24h) formats are based on the format in your OS.

Moon position

The coordinates of the Moon can be calculated using astronomical algorithms that take into account the position of the Moon relative to the Earth and the Sun, as well as other factors such as the Moon's orbit, libration, and parallax.

To calculate the Moon's coordinates, you will need to know the date and time for which you want to determine the Moon's position. You will also need to know your location on the Earth, as this can affect the Moon's apparent position due to parallax.

Once you have this information, you can use this online tool that incorporates the necessary algorithms to calculate the Moon's coordinates.


An online precise moon coordinates calculator tool is a web-based application that allows users to determine the precise celestial coordinates of the moon for a specific date and time. These coordinates can be expressed in terms of the moon's right ascension and declination, which describe the moon's position in the sky relative to the celestial equator and the vernal equinox.

This tool may offer features such as the ability to input a specific date and time, and provide real-time or historical data about the moon's coordinates, as well as lunar altitude and azimuth, distance, libration, and parallax.

A precise moon coordinates calculator can be a useful resource for astronomers, astrophotographers, and other individuals who need to accurately locate the moon in the sky. By providing detailed and accurate information about the moon's position, this tool can help users plan observations, track lunar events, and deepen their understanding of the Earth-moon system.
