Answer:
1. This discovery included Pluto in a newly created family of dwarf planets. It also forced the International Astronomical Union to redefine the term planet.
2. The demotion of Pluto to dwarf planet was caused by the discovery of Eris, a minor body that is larger than Pluto. This discovery triggered important events in the history of science. It also proved that there are still many objects to be discovered in the solar system. Therefore, this was a positive development.
3. This discovery was controversial to a small degree because it challenged a widely accepted belief that Pluto was a planet. However, Pluto was discovered less than a century ago, and people showed little resistance to accepting the change.
4.This discovery can be linked to the developments made in astronomy during the Scientific Revolution. It’s somewhat similar to what happened when Copernicus presented his heliocentric theory. He disputed Ptolemy’s accepted theory that Earth was the center of the solar system. Copernicus argued that the Sun was the center and that Earth and the other planets revolved around it. Both discoveries triggered more research in the field of astronomy.

Answer:
A. The discovery had put Pluto in a new group that had consisted of dwarf planets. It also pushed the IAU to reanalyze the word planet.
B. I think that this was a positive development because of the discovery of Eris, which was a body that is bigger than Pluto. With this discovery it impacted important events in the history of sciences. It also showed that there are still many things to discover in the solar system.
C. Yes, with the discovery it challenged people's acceptance belief that Pluto was a planet. Pluto was discovered and found less than one hundred years ago, and people show the resistance of accepting the change in that planet.
D. I think that this discovery can be linked to the developments in astronomy . I know that this is somewhat similar to what had happened when Copernicus showed his theory. He debated someone's theory that Earth was the center of all the solar system. Copernicus proclaimed that the Sun was the center of the Earth and that the other planets in the solar system are revolving around it. Both of these discoveries triggered more research in Astronomy.
