Astronomical Distance Quotes

Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.

All we ever see of stars are their old photographs.

And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don’t even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don’t have to take them into account when you are calculating something.

The Stars are a long way off, and their words get somewhat dulled in the message.

Staring at the stars was like staring backward in time, since some stars are so far away that their light takes millions of years just to reach us. That we see stars not as they look now, but as they were when dinosaurs roamed the earth. The whole concept just struck me as…amazing somehow.

Living in Manchester was like living on the moon... wherever that might be

Oskar Schell: If the sun were to explode, you wouldn't even know about it for 8 minutes because thats how long it takes for light to travel to us. For eight minutes the world would still be bright and it would still feel warm. It was a year since my dad died and I could feel my eight minutes with him... were running out.

The stars are so far, far away!

I can feel the universe expanding and making things be further apart.

I cannot possibly conceive of my planet Earth as the centre of a three-tiered universe. I know rather that the sun, around which my planet Earth revolves, is a middle sized star in a galaxy called the Milky Way that has over a hundred billion other suns or stars within it.

The sun is the most parallel light source because it is so far away.

The problem here is that a civilization that is 1,000 light years away doesn't know we exist. They don't know that we have radio telescopes here on Earth because they see Earth as it was 1,000 years ago. Nothing can travel faster than light, so however good their instruments they can't see in affect the future. So there is no particular reason they should be sending us messages at this time.

Two hundred miles from the surface of the earth there is no gravity. The laws of motion are suspended. You could turn somersaults slowly slowly, weight into weightlessness, nowhere to fall. As you lay on your back paddling in space you might notice your feet had fled your head. You are stretching slowly slowly, getting longer, your joints are slipping away from their usual places. There is no connection between your shoulder and your arm. You will break up bone by bone, fractured from who you are, drifting away now, the centre cannot hold.

Many different planets are many different distances from their host star; we find ourselves at this distance because if we were closer or farther away, the temperature would be hotter or colder, eliminating liquid water, an essential ingredient for our survival.

The pinpoints of starlight we see with the naked eye are photons that have been streaming toward us for a few years or a few thousand.

Mars is there, waiting to be reached.

There’s something about sitting alone in the dark that reminds you how big the world really is, and how far apart we all are. The stars look like they’re so close, you could reach out and touch them. But you can’t. Sometimes things look a lot closer than they are.

Here's a question we all ask ourselves at least once when we're young: Where does that starlight come from? It's been there before I was born, and before my grandmother, and her grandmother were born. So just how far is that star from Earth?

The heavenly light you admire is fossil-light, it's the unfathomably distant past you gaze into, stars long extinct

If you think that the distance from the Earth to the nearest planet where we could live comfortably... is being, like, from New York to Australia... what we've achieved so far, in going to the moon, that's about two-and-a-half inches. So that's the challenge.

The Earth reminded us of a Christmas tree ornament hanging in the blackness of space. As we got farther and farther away it diminished in size. Finally it shrank to the size of a marble, the most beautiful marble you can imagine.

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.

I mean astronomically, that one doesn't even make sense. Because if you shoot for the moon, you're not going to land on the stars. The moon is closer than all of the stars.

Space is about 100 kilometers away. That’s far away—I wouldn’t want to climb a ladder to get there—but it isn’t that far away. If you’re in Sacramento, Seattle, Canberra, Kolkata, Hyderabad, Phnom Penh, Cairo, Beijing, central Japan, central Sri Lanka, or Portland, space is closer than the sea.

A million million million million (1 with twenty-four zeros after it) miles, the size of the observable universe.
