why do astronomers say that terrestrial planets are comomn in our galaxy?
UF,
s In 2014, astronomers discovered 22 new KBOS, among those the following three: 2014
with a period of 331.1 years; 2014 TT, with a period of 280.8 years; 2014 QM
with a period of 315.2 years. Given that information and knowing that Neptune's period is
85
441
164.8 years, which of those objects - if any- are likely part of the Plutino family of KBOS?
Show your work that lead you to your conclusion.
Imagine a trans-Neptunian object with roughly the same mass as Earth but located 50 AU from the sun. a) based on the solar nebula theory, what do you think this object would be made of and why? b) on the basis of speculation, assume a reasonable density for this object and calculate its diameter in units of Earth radii.
