Meanwhile, enormous ground - based observatories like the Giant Magellan Telescope in Chile and the Thirty Meter Telescope in Hawaii, both scheduled to open their eyes around 2020, will perform the more time - consuming work of measuring the masses and densities of the planets found by TESS to determine whether they are rocky objects, gassy ones, or something else entirely.

In the second paper, physicist Dejan Vinković of the University of Split in Croatia developed a model that shows how a combination of stellar wind and infrared radiation from the inner disk can blow the ultrafine crystallized silicate particles billions of kilometers from the inner regions of a protoplanetary disk to its colder outer sections, where comets and other cold but rocky objects, such as Pluto, can form.

This is most obvious with planets with a large atmosphere (so - called «hot Jupiters») but harder to see with the rockier objects.
