Why Do We Use The Astronomical Unit To Measure Distances In The Solar System Rather Than The Light Year? Answer 2: The solar system is enormous, and interstellar space is even bigger. One astronomical unit is equal to 150 million kilometers. This makes it much easier to count the distances if they’re in counts of
Why Do We Use Light Years To Measure The Distance Of The Celestial Bodies? Measuring in light-years also allows astronomers to determine how far back in time they are viewing. Because light takes time to travel to our eyes, everything we view in the night sky has already happened. In other words, when you observe
How Do You Find The Orbital Period Of AU? If the size of the orbit (a) is expressed in astronomical units How do you find the orbital period? The orbit formula, r = (h2/μ)/(1 + e cos θ), gives the position of body m2 in its orbit around m1 as a function of the true
Is Achernar A Giant? Achernar has around 6.3 solar masses, a radius of about 7.3 x 11.4 solar radii, and an average diameter of more than 10 times that of our Sun. Achernar spins around 15 times faster than our sun, completing one rotation in around 2 days. Is achernar a white dwarf? Star System
What Are The Rungs Of The Distance Ladder? In this paper, we determine the sizes of the first three rungs of the cosmological distance ladder, the radius of the Earth, the distance to the Moon, and the distance to the Sun. The first two distances can be obtained without a telescope. What is the final
What Is The Average Distance From The Sun In AU Of An Asteroid With An Orbital Period Of 8 Years? E. planets have circular orbits. From Kepler’s third law, an asteroid with an orbital period of 8 years lies at an average distance from the Sun equal to A. 4 astronomical units B. What is
