Francesco Carlini facts for kids
Francesco Carlini was an important Italian scientist. He was born in Milan on January 7, 1783. Carlini became famous for his work as an astronomer. He studied the stars, planets, and other objects in space.
In 1832, Carlini became the director of the Brera Astronomical Observatory in Milan. An observatory is a special place with powerful telescopes to watch the sky. As director, he led many important studies about space.

Carlini's Work on the Sun
Francesco Carlini wrote several books about astronomy. These books helped other scientists understand the movements of the sky.
Early Writings on Astronomy
In 1810, Carlini published a book called Esposizione di un nuovo metodo di construire le tavole astronomiche applicato alle tavole del sole. This long title means he showed a new way to create tables for astronomy. These tables helped predict how the Sun would appear to move.
Later Sun Tables
Later, in 1832, he published another important book. It was titled Nuove tavole de moti apparenti del sole. This book also focused on the Sun's movements. Carlini's work helped improve how astronomers tracked the Sun.
Measuring the Earth
One of Carlini's most exciting projects involved measuring the Earth itself. He worked with another scientist named Giovanni Antonio Amedeo Plana.
The Geodetic Project
Together, they joined a "geodetic project." Geodesy is the science of measuring Earth's shape and size. This project took them to Austria and Italy. They wanted to make very accurate maps and understand our planet better.
Pendulum Experiment on Mount Cenis
During their trip in 1821, Carlini did a special experiment. He took pendulum measurements on top of Mount Cenis in Italy. A pendulum is a weight hanging from a string that swings back and forth. How fast a pendulum swings can tell you about the gravity in that spot.
From these measurements, Carlini made a big discovery. He calculated one of the first good estimates for the density and total mass of our planet. This was a huge step forward in understanding Earth's physical properties.
Legacy and Recognition
Francesco Carlini passed away in Milan on August 29, 1862. His work left a lasting mark on astronomy and geodesy.
Carlini Crater on the Moon
To honor his contributions, a crater on the Moon is named after him. It is called Carlini Crater. This shows how important his discoveries were to the world of science.
