🔭 Famous Interstellar Object that Passed through our Solar System
The name of the famous interstellar object that passed through our solar system is Oumuamua. It was first detected on October 19, 2017, by the Pan-STARRS1 telescope in Hawaii, and its unusual trajectory and characteristics led astronomers to conclude that it came from outside our solar system. The name Oumuamua comes from Hawaiian, meaning "scout" or "messenger" sent from the distant past to reach out to us. It is believed to be an elongated object, about 800 meters long and only 80 meters wide, and was traveling at a speed of around 315,000 kilometers per hour when it passed closest to the Sun in September 2017. Its origin and composition remain a subject of much scientific debate and speculation.

🔭 Fundamental Units of Distance
Early measurements of length were based on human dimensions, but today, we use worldwide standards that specify lengths in units such as the meter. Distances within the solar system are now determined by timing how long it takes radar signals to travel from Earth to the surface of a planet or other body and then return.

♞ Hubble’s Law
The more distant the galaxy, the faster it was receding from us.
Written as a formula, the relationship between velocity and distance is
v = H × d
where v is the velocity,
d is the distance, and
H is a number called the Hubble constant.
This equation is known as Hubble’s law.
