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 what is the angular size of its image in this telescope?

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

Alpha Centauri is the closest star system and planetary system to our Solar System at 4.24 light-years from the Sun. A NASA spacecraft, Deep Space 1 (DS1), can travel in deep space at a top speed of 35,000 mph, how many years would it take DS1 to reach Alpha Centauri? Assuming light travels at a speed of 299,792,458 meter per second and 1 mile = 1609 meters.

1. Alpha Centauri is the closest star system to our Solar System at a distance of 4.37 light-years. The velocity of light is 3.00 x108 m/s and a light year is defined as the distance light travels in 1 year. Calculate the distance in kilo meters (km) from Alpha Centauri to our Solar System in Scientific Notation format with the correct number of significant figures.

Proxima Centauri, the closest star to us besides our own Sun, is 4.10 x 1013 km from Earth. From Zorg, a planet orbiting this star, Gregor places an order at Tony's Pizza in Hoboken, New Jersey, communicating by light signals. Tony's fastest delivery craft travels at 1.00 × 104c (The speed of light, designated by the universally recognized symbol c, has a value of 3.00 x 108 m/s).
