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 International Space Federation constructs a new spaceship that can travel at a speed of 0.980c. Mary, the astronaut, boards the spaceship to travel to Barnard's star, which is the second nearest star to our solar system after Alpha Centauri and is 5.98 ly away. After reaching Barnard's star, the spaceship travels slowly around the star system for 6 years doing research before returning back to Earth. (a) How much time does the journey take? years (b) How much older...
Light requires 4.5 years to travel from the nearest star to earth
Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?

a) Consider a star with the same ass as our sun but with a different radius. To escape this stur an object launched from its surface needs a speed equal to the speed of light (3 x 10m/s). What is the radius of this star? b) A satellite with mm Sooky is launched into orbit from Earth's surface. If the satellite travels in a circular orbit with speed 7000 m/s what was the speed of the satellite when it was...

A binary star system has two stars, each with the same mass as our sun, separated by 1.50×1012 m . A comet is very far away and essentially at rest. Slowly but surely, gravity pulls the comet toward the stars. Suppose the comet travels along a straight line that passes through the midpoint between the two stars. What is the speed at the comet's midpoint?

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.

PartA Constants Suppose a star the size of our Sun, but with mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 12 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume also that the thrown-off mass carries off either no angular momentum Express your answer using two significant figures. A2c rev/s Part B...

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).
