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 heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs. The left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart.
