A Quote by Neil deGrasse Tyson

Once you've got the makings of a star, gravity draws leftover gas and dust into a giant swirling disk. The dust continues to stick together, clumping into rocky asteroids, which eventually become orbiting rocky planets. And voila: a solar system!

Gather out of star-dust, Earth-dust, Cloud-dust, Storm-dust, And splinters of hail, One handful of dream-dust, Not for sale.

Langston Hughes

But one of the coolest things about meteorites is that most were formed four-and-a-half-billion years ago, during the birth of our solar system, when, for reasons not yet known, a cloud of gas and dust was transformed into a sun with circling planets.

Neil deGrasse Tyson

The gas-giant planets in our solar system all have large moons.

Debra Fischer

No matter how you measure it, whether you measure the amount of mass or you measure the number of bodies, most of our solar system exists out beyond the orbits of the asteroids. So we could not have claimed to know our own solar system until Voyager had toured the giant planets.

Carolyn Porco

The Kuiper belt region, which I call the third zone because it lies beyond the rocky terrestrial planets and beyond the giant planets, is a bizarre frontier.

Alan Stern

Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.

Jill Tarter

A major puzzle for which nobody has an answer is this: is there some size at which the planets change their nature from water-rich planets like Neptune, to rocky planets like the Earth? We have found two planets that are the size of the Earth in radius, but they are very close to their host star, so water on the surface would evaporate away.

Geoffrey Marcy

Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other very Earth-like planets in our solar system, meaning they orbit close to the sun; they have rocky surfaces and thin atmospheres.

David Grinspoon

Because Alpha Centauri is so close, it is our first stop outside our solar system. There's almost certain to be small, rocky planets around Alpha Centauri A and B.

The genius' behind the new Rocky movie decided to call it Rocky Balboa so that we'll probably forget that it's number six. Or Rocky Balboa can't count past five.

Doug Benson

Spring is the usual period for house-cleaning and removing the dust and dirt which, notwithstanding all precautions, will accumulate during the winter months from dust, smoke, gas, etc.

Isabella Beeton

I wanted to be a snowplow driver when I was a kid. Growing up in the Rocky Mountains, that's the most glorious job you can imagine. But then my mother took me to a lecture about the solar system when I was 8, and I got hooked.

Kip Thorne

The stars associated with the solar system, such as the planets and asteroids (and it should be remembered that the term star in Biblical usage applies to any heavenly body other than the sun and moon) would be particularly likely to be involved, in the view of the heavy concentration of angels, both bad and evil, around the planet Earth.

Henry M. Morris

We are all made from star dust and we will all return to star dust, like a cosmic palindrome.

A.S. King

Discovering that our solar system has many more planets than we ever expected, and that most of them are ice dwarfs rather than like Earth and the other rocky terrestrials, is just another step in the revolution in viewpoint that removed the Earth from the center of the physical universe and makes Earth all the more special.

Alan Stern

In 1999, my team discovered that the star Upsilon Andromedae was circled by three gas-giant planets - the first distant multiplanet system ever found. That same year, other researchers observed the first 'transit' of an exoplanet - a planet blocking out a small fraction of the starlight as it passes in front of the star.
