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.

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.
Alpha Centauri, the binary star closest to our solar system, is about 4.0 ly away. If a spaceship traveled this distance with a constant speed of 0.85c relative to Earth, how much time would elapse (a) on a clock on the spaceship? Ans in Years
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...
In solar Astronomy the standard unit of measurement for distance is the Astronomical Unit which is the average distance from the Earth to the Sun ( 1 1.5 10 ) 8 AU = km . In stellar Astronomy the distances are so large, that the standard units of length are the Light Year (LY) or the Parsec. A light year is the distance traveled by light in one year, know that light travels 300000 km per second in empty...
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). (a) How long does it take Gregor's order to reach Tony's Pizza?...
PLEASE ANSWER BOTH!!! Our best measurements from Earth indicate that the star system Alpha Centauri is 4.2 light-years away. Suppose some of our astronauts traveled there at a speed v 0.83c. What would the astronauts measure as the distance to Alpha Centauri? O 2.8 light-years 9.1 light-years O 2.9 light-years O 2.3 light-years O 7.5 light-years If a proton with mass 1.67 x 10"27 kg moves in an accelerator such that its total energy is five times its rest energy...

ANSWER 3A, B, AND C! 3. The star system that is closest to the earth is Alpha Centauri. It is 4.37 light years away in Earth's reference frame. The fastest spacecraft humans have ever launched is New Horizons, which sent us sweet pictures of Pluto in 2015. It attained a speed of 45 km/s relative to the sun. That's fast, but even at this rate, interstellar travel is not practical. a) Traveling at 45 km/s, how long, in years, would...
A new extrasolar planet (outside our solar system) has been discovered. This planet orbits a star of mass 1.03×1031 kg with a period of 6.52 years .

Python 3 Write a function named starCounter that takes three parameters: 1. a dictionary named starDictionary. Each key in starDictionary is the name of a star (a string). Its value is a dictionary with two keys: the string 'distance' and the string 'type'. The value associated with key 'distance' is the distance from our solar system in light years. The value associated with key 'type' is a classification such as 'supergiant' or 'dwarf'. 2. a number, maxDistance 3. a string,...
