Pluto Day celebrated worldwide on February 18 every year. Pluto was discovered in 1930 by Clyde Tombaugh. This celestial body was considered the ninth planet of the solar system for about 76 years, but after 1992 its status as a planet began to be questioned, as many objects such as Pluto with similar sizes were discovered in the Kuiper Belt (one of the regions of the solar system systems). On August 24, 2006, the International Astronomical Union (IAU) downgraded Pluto to a dwarf planet. This new “planet” status is still not accepted by a number of scientists who continue to consider Pluto as a full-fledged planet in our system.

And really, after so many years spent searching for this planet, it’s only natural to think that Pluto deserves to remain a planet, right? Pluto very far from Earth, so relatively little is known about this planet. Pluto got its name in honor of the god of the underworld in Roman mythology. The surface temperature is estimated to be approximately -233 to -213 Celsius. The approximate distance from Pluto to the Sun is almost 6 billion km. This planet is two-thirds the size of our Moon.

The best way to celebrate Pluto Day is to learn as much as possible about this planet (yes, we said PLANET :). You can visit your nearest planetarium and not only learn, but also see Pluto with your own eyes. With the hashtag #PlutoDay, you can share your photos and thoughts about Pluto and read the opinions of other people from all over the world.
