A Quote by Seth Shostak

The planets and moons of our solar system are blatantly visible because they reflect sunlight. Without the nearby Sun, these planets would be cryptic and dark on the sky.

When I grew up as a kid, we didn't know there were any other planets outside of our own solar system. It was widely speculated that planet formation was an incredibly rare event and that it's possible that other planets just don't exist in our galaxy, and it's just this special situation where we happen to have planets around our sun.

John M. Grunsfeld

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

Debra Fischer

Before 1995, the only planets we knew about were the planets in our solar system.

Debra Fischer

Our solar system is actually a wild frontier, teeming with different, diverse places: planets and moons, millions of objects of ice and rock.

Carrie Nugent

There's no doubt that the search for planets is motivated by the search for life. Humans are interested in whether or not life evolves on other planets. We'd especially like to find communicating, technological life, and we look around our own solar system, and we see that of all the planets, there's only one that's inhabited.

Debra Fischer

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

Our solar system is fantastically bizarre. There are worlds with features we never imagined. Storms larger than planets, moons with under-surface oceans, lakes of methane, worldlets that swap places...and that's just at Saturn.

Phil Plait

Just as our solar system has a certain idiosyncratic assortment of planets and moons, different from any neighboring system yet categorically equivalent, so each distinct period of human history might have special qualities and individuals, characteristics and events, yet still be essentially akin beneath the surface to all the others.

Paul Di Filippo

Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.

This is in a real sense the capstone of the initial missions to explore the planets. Pluto, its moons and this part of the solar system are such mysteries that New Horizons will rewrite all of the textbooks.

Alan Stern

We're just learning that a lot of planets are small planets, and we didn't know that before, fact is, in planetary science, objects such as Pluto and the other dwarf planets in the Kuiper Belt are considered planets and called planets in everyday discourse in scientific meetings.

Alan Stern

When Hubble was launched, it became clear very shortly thereafter that there was a problem with the optics.The mirror was not quite the right shape. And the one program that I had really been looking forward to doing with Hubble was studying outer planets in our solar system, the planets Uranus and Neptune.

Heidi Hammel

In future, children won't perceive the stars as mere twinkling points of light: they'll learn that each is a 'Sun', orbited by planets fully as interesting as those in our Solar system.

Martin Rees

Outside intelligences, exploring the Solar System with true impartiality, would be quite likely to enter the Sun in their records thus: Star X, spectral class G0, 4 planets plus debris.

Isaac

Our sun enlightens the planets that belong to him; why may not every fixed star also have planets to which they give light?

Bernard le Bovier de Fontenelle

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
