775 Lumière is a small space rock, also known as a minor planet, that orbits our Sun. It's part of a huge group of objects found mostly between Mars and Jupiter. This particular minor planet is about 33.58 kilometers (around 21 miles) wide.

What is 775 Lumière?
775 Lumière is an asteroid, which is a type of minor planet. It's not a big planet like Earth or Mars. Instead, it's a rocky body that is much smaller. It travels around the Sun, just like the planets do.
How Bright is It?
When we look at 775 Lumière from Earth, its brightness is measured by something called apparent magnitude. For 775 Lumière, this is 10.40. The smaller the number, the brighter an object appears. Since 10.40 is a higher number, it means 775 Lumière is quite dim. You would need a telescope to see it.
How Does It Spin?
Every object in space spins, and 775 Lumière is no different. It completes one full spin, which is called its rotational period, in about 6.103 hours. That's a little over six hours. Imagine a day on this asteroid lasting only six hours!
How Reflective is It?
The surface of 775 Lumière reflects some sunlight. How much light it reflects is called its albedo. For 775 Lumière, its albedo is 0.108. This means it reflects about 10.8% of the sunlight that hits it. A lower albedo means it's quite dark, like a piece of charcoal.
Discovery of 775 Lumière
This minor planet was first spotted a long time ago. It was discovered by an astronomer named J. Lagrula.
When and Where Was It Found?
J. Lagrula found 775 Lumière on January 6, 1914. This discovery happened at the Nice Observatory, which is a famous place for studying space in France.
Why is it Called "Lumière"?
The name "Lumière" was chosen to honor two very important people: Auguste and Louis Lumiere. They were brothers from France who were pioneers in photography and filmmaking.
A Nod to Photography
The Lumiere brothers were famous for their work with photographic film. This was very important for astronomers too, as they used film to capture images of space. Naming the asteroid "Lumière" was a way to recognize their contributions to science and technology, especially in photography, which helped astronomers see the universe better.
