Bura, also known as Etra b, CelWP M2 b, or WI 135643 b is the first and largest planet around the pulsar Etra. It has no moons and was released in CelWP Release 7 along with the rest of the Etra system.

Physical Characteristics[edit | edit source]

Bura is a hot jupiter, which is a near jupiter mass planet orbiting close to its star. Because of this, Bura has a huge effect on the orbits of the other planet in the system, Palsa, causing its orbit to rapidly precess. The large amount of high-frequency radiation from the pulsar makes the planet heat up and expand, making it larger than normal.

The high temperature also causes fierce winds, causing shifting cloud patterns on this planet, making it rather difficult to construct cloud bases on them, even after temperature adjusting is taken into account.

Atmosphere[edit | edit source]

Bura's atmosphere is an extremely hot envelope of gases that constantly whip across the planet at high speeds. The extreme pressure difference on the two sides of Bura, caused by the extreme pressure difference caused by its tidal locking, drives winds that commonly surpass twice the speed of sound. On the day side, the atmosphere turns into plasma after being heated to extreme temperatures. Meanwhile, the night side of the planet radiates this heat away and condenses back into cooler gases, causing the worldwide ridiculous pressure gradient that drives the winds. Its clouds are divided into five different cloud terranes - the dayside cloud belts, nightside cloud belts, dayside cloud zones, nightside cloud zones, and the clear belts.

Orbit and Rotation[edit | edit source]

This planet recently formed in close to its present location after the Etra Supernova destroyed the planets in the old system. However, scientists dont presently know much about this system's history, and as such, this is not confirmed. Bura is also tidally locked and is not known to possess any large moons.
