Breaking News There’s an Earth-like Planet Next Door!

Astronomers have confirmed the existence of Proxima B, an Earth-like exoplanet orbiting Proxima Centauri, our closest stellar neighbor. Proxima B is a rocky planet with 1.3 times Earth's mass, located 4.24 light-years away. It orbits a red dwarf star closely, potentially allowing for liquid water. The discovery was confirmed through extensive observations of the star's Doppler shift, ruling out star spots as a cause. Despite its proximity, Proxima B's habitability remains uncertain due to unknown atmospheric conditions and radiation exposure. Future research aims to study its atmosphere using advanced telescopes like TESS and the James Webb Space Telescope.

What is the mass of Proxima B compared to Earth?

• 0.5 times the mass of Earth

• 1.3 times the mass of Earth

• 3 times the mass of Earth

• 2 times the mass of Earth

What method was primarily used to confirm the existence of Proxima B?

• Transit photometry

• Doppler shift analysis

• Gravitational microlensing

• Direct imaging

What phenomenon was ruled out as a cause for the observed Doppler shift in Proxima Centauri?

• Cometary activity

• Planetary transits

• Star spots
