New Horizons launched on January 19, 2006, and itâll reach Pluto on July 14, 2015. Do a little math and youâll find that it has taken 9 years, 5 months and 25 days. The Voyager spacecraft did the distance between Earth and Pluto in about 12.5 years, although, neither spacecraft actually flew past Pluto.luto travels on a highly elliptical orbit around the Sun. At its closest point, known as âperihelionâ, Pluto is only 4.4 billion kilometers out. Thatâs nearly 30 AU, or 30 times the distance from the Earth to the Sun.
The LAD gives rise to the following two sets of branches: 1  The diagonals are branches of the LAD that runs diagonally away from the LAD and towards the left edge in front of the heart. 2  The septal perforators (SP) runs into the septum (partition that separates the two ventricles) and provides its blood supply.
The left main coronary artery (LMCA) arises from the left aortic sinus, running towards the left hand side of the heart, just below the left auricle. It quickly divides into the anterior interventricular branch also known as the left anterior descending (LAD) artery and the circumflex artery.The LAD runs along the anterior interventricular sulcus, a groove in the anterior surface of the heart that seperates the left and right ventricle, down towards the apex.rom here, it curls around towards the inferior surface of the heart, forming the posterior interventricular branch, more commonly known as the posterior descending artery (PDA). The PDA runs along the posterior interventiculas sulcus, to supply blood to the walls of both the left and right ventricle.
