Introduction to the Pluto system science special issue, published by Elsevier Inc. in 2015, is considered as an academic journal. The first paragraph notice the Pluto in detail. The Pluto orbit in an average 39.44 AU from the Sun and have a high eccentricity, have a radius of 1137km which is much smaller than the Moon. For the article I’m evaluating, it indicate that the Pluto’s aphelion is about 4.6 billion miles (50.13 AU). The diameter is about 1500 miles (2400 km), we can tell it’s about 1200km in radius, which is extraordinary close to the accurate number. For this time, the article use a creditable number in the …show more content…
Klahr Hubert, Brandner Wolfgang, Jakosky Bruce. These three people are positively expert of Astronomy, especially Jakosky Bruce, the leader of the University of Colorado at Boulder team within the NASA Astrobiology institute, has authority to define the planet and his book the extremely high credibility. In this powerful resource, we can find some really interesting facts of the dwarf planet: The dwarf planets are usually less massive than planets, with an irregular orbit around the star. This is exactly what the article means in its third part, which means that the article is extremely precise in this part of crucial research. I reckon this part as valuable source for scholar
