The nearest star to Earth besides the Sun is Proxima Centauri, which is a distance of approximately 4 light years away. A planet that may be able to sustain liquid water on its surface was discovered in 2016 orbiting Proxima Centauri. According to observers on Earth, a spaceship that travels at 0.9c should be able to reach the planet in 3.6 years. How long would the trip take according to astronauts on board the spaceship?

The closest star to our Sun (Proxima Centauri is about 4.0 x 1016 m away. It has a planet (Proxima b)in orbit around it at about 1/20 of the radius of Earth's orbit around our Sun. Estimate the minimum diameter D of the aperture of a space telescope that would be required to resolve Proxima b from its star, for light in the visible part of the spectrum

The closest star to our solar system is Proxima Centauri, with a diameter of 2.0 x 10^8 m (about 1/3 that of the sun) and a distance of 9.5 x 10^15 m (4.2 light years). The world’s largest optical telescope is Gran Telescopio Canarios, with an objective mirror with a diameter of 10.4 m and focal length 16.5 m. The effective focal length of the imaging lens = 11.8 cm. What angle does Proxima Centauri subtend in the sky and...
