What is the significance of the discovery of the exoplanet with a temperature of -200 degrees Celsius?

The recent discovery of an exoplanet with a temperature of -200 degrees Celsius is significant because it provides valuable insights into the icy worlds that exist beyond our solar system. The exoplanet, named OGLE-2016-BLG-1195Lb, is located over 13,000 light-years away in the constellation Scorpius.

Researchers used a technique called microlensing to discover the planet. Microlensing occurs when a foreground object, such as a planet, passes in front of a background star, causing the light from the star to be magnified and allowing scientists to detect the planet's presence.

The extreme cold of OGLE-2016-BLG-1195Lb is due to its distance from its parent star. The exoplanet is so far away that it takes over three Earth years to complete a single orbit.

The discovery of this frigid exoplanet sheds light on the range of planetary environments that exist beyond our solar system. It also provides scientists with another data point to help refine our understanding of the different types of exoplanets that exist and the conditions that are necessary for their formation and survival.
