Move Over Pluto, Astronomers Say There's a New Planet in Town Ten years ago, astronomer’s shrunk the solar system by removing Pluto from the list of real planets. Now the solar system is getting bigger again. Artistic rendering of the distant view from Planet Nine back towards the sun. The planet is thought to be gaseous, similar to Uranus and Neptune.

Pluto Demoted Last year, astronomers at Cal Tech discovered an object they called Xena--even bigger than Pluto, and also orbiting around the Sun. That set off an astronomical controversy. Are there really 10 planets? Today, the International Astronomical Union said, "No." Xena isn't a planet at all, and neither is Pluto. Planetary astronomer Mike Brown led the CalTech team that discovered Xena . (An extended discussion on this subject was originally aired earlier today on To the Point.)
Pluto, Planet or Plan Not? Since Pluto's discovery in 1930, there have been nine planets in the solar system, but a year ago, scientists at the California Institute of Technology said there were ten. An object they called Xena turned out to be bigger than Pluto and was also orbiting around the Sun. That set off an astronomical controversy that wasn't resolved until today, thanks to the International Astronomical Union . Planetary scientist Mike Brown led the Cal Tech Team that discovered Xena.
'Do-or-die' time on healthcare bill President Trump has demanded a House vote today on replacing Obamacare…whatever the details might be. Despite his campaign promise that nobody would lose health insurance, that's possible for 24 million people if he were finally to sign this bill into law.
Trump's travel ban and the long-term agenda The Trump Administration's revised travel ban may be good news for some visa holders and others, but it's still being challenged as unconstitutional. Some reporters call it the beginning of a long-term effort to change the demographic make-up of the United States.
House Republicans release their Obamacare replacement As two House committees take up "repeal and replacement" of "Obamacare," there may be life left in the Affordable Care Act after all. Even Republicans are divided, and proposed changes won't make good on President Trump's promise to provide "health insurance for everybody."
