Some engines also began using locally available vegetable oils as a substitute for diesel to tide over the hostage of petro-diesel. In a âDiesel Engine Exhibitâ in Paris in the year 1900, which was attended by 50 million people, Rudolfâs engine was fueled with peanut oil and the engine ran quite successfully.
The third star, which may or may not be part of the system, is Proxima Centauri. It is about 4.22 light-years from Earth and is the closest star other than the sun. Alpha Centauri A and B orbit a common center of gravity every 80 years.The average distance between them is about 11 astronomical units (AU) â about the same distance as the sun is to Uranus.These stars are an average of 4.3 light-years from Earth.lpha Centauri A and B orbit a common center of gravity every 80 years.

The Sun is really the closest star at 150,000,000 km (93,000,000 miles). Proxima Centauri is the closest star to us, at a distance of approximately 4.2 light years. (Proxima is Latin for next to or nearest to).Alpha Centauri is the closest star system to us at a distance of approximately 4.3 light years.he same distance as Earth's nearest star-roughly 90 million miles; it is the Sun.       Since the Moon is in the same relative position as earth (separated by on â¦ ly 1.2 light SECONDS) it would be Proxima Centauri at 4.2 light Years.     EDIT: looks like I fail since it is the Sun and not Proxima Centaur.
