The video introduces 55 Cancri e, an exoplanet known as the 'diamond planet' due to its carbon-rich composition. Discovered in 2004 by astronomer Barbara MacArthur using radial velocity, it orbits a G-type star 40 light-years from Earth. The planet has a mass 8.08 times that of Earth and completes an orbit in 0.7 days. It belongs to the Cancer constellation. In 2016, NASA's Hubble detected hydrogen and helium in its atmosphere. The planet is tidally locked, with a dayside temperature of 4200°F. Future exploration of its host star's system is anticipated.
