Size Comparison Of Astronomical Objects

Top row: Uranus and Neptune; second row: Earth, the white dwarf Sirius B, Venus; bottom row (reproduced and enlarged in lower image)—above: Mars and Mercury; below: the Moon, dwarf planets Pluto and Haumea

Mars (back left), Mercury (back right), Moon (front left), Pluto (front center), and Haumea (front right), to scale.

Planets of the Solar System (Sizes to scale; distances and illumination not to scale)

The inner planets. From left to right: Mercury, Venus, Earth and Mars in true-color. (Sizes to scale; distances not to scale)

The gas giants against the Sun's limb, at 1 px = 1 Mm The diameters are to scale. The limb of the Sun is in the background. From left to right, Jupiter, Saturn, Uranus and Neptune.

The Location of the Earth in the Solar System

The Location of the Solar System in the Milky Way Galaxy

Artist's conception of the spiral structure of the Milky Way with two major stellar arms and a bar

This detailed annotated artist’s impression shows the structure of the Milky Way, including the location of the spiral arms and other components such as the bulge. This version of the image has been updated to include the most recent mapping of the shape of the central bulge deduced from survey data from ESO’s VISTA telescope at the Paranal Observatory.

Image of the night sky above Paranal on 21 July 2007, taken by ESO astronomer Yuri Beletsky. A wide band of stars and dust clouds, spanning more than 100 degrees on the sky, is seen. This is the Milky Way, the Galaxy we belong to. At the centre of the image, two bright objects are visible. The brightest is the planet Jupiter, while the other is the star Antares.

2. And this is where you live in your neighborhood, the solar system.

3. Here’s the distance, to scale, between the Earth and the moon. Doesn’t look too far, does it?

4. THINK AGAIN. Inside that distance you can fit every planet in our solar system, nice and neatly.

5. But let’s talk about planets. That little green smudge is North America on Jupiter.

6. And here’s the size of Earth (well, six Earths) compared with Saturn:

7. And just for good measure, here’s what Saturn’s rings would look like if they were around Earth:

8. This right here is a comet. We just landed a probe on one of those bad boys. Here’s what one looks like compared with Los Angeles:

9. But that’s nothing compared to our sun. Just remember:

10. Here’s you from the moon:

11. Here’s you from Mars:

12. Here’s you from just behind Saturn’s rings:

13. And here’s you from just beyond Neptune, 4 billion miles away.

To paraphrase Carl Sagan, everyone and everything you have ever known exists on that little speck.

14. Let’s step back a bit. Here’s the size of Earth compared with the size of our sun. Terrifying, right?

The sun doesn’t even fit in the image.

15. And here’s that same sun from the surface of Mars:

NASA

16. But that’s nothing. Again, as Carl once mused, there are more stars in space than there are grains of sand on every beach on Earth:

Via science.nationalgeographic.com

17. Which means that there are ones much, much bigger than little wimpy sun. Just look at how tiny and insignificant our sun is:

Via en.wikipedia.org

Our sun probably gets its lunch money stolen.

18. Here’s another look. The biggest star, VY Canis Majoris, is 1,000,000,000 times bigger than our sun:

Via youtube.com

19. But none of those compares to the size of a galaxy. In fact, if you shrank the sun down to the size of a white blood cell and shrunk the Milky Way galaxy down using the same scale, the Milky Way would be the size of the United States:

20. That’s because the Milky Way galaxy is huge. This is where you live inside there:

Via teecraze.com

21. But this is all you ever see:

Via Twitter: @lucybrockle

(That’s not a picture of the Milky Way, but you get the idea.)

22. But even our galaxy is a little runt compared with some others. Here’s the Milky Way compared to IC 1011, 350 million light years away from Earth:

Via Twitter: @smokeinpublic

Just THINK about all that could be inside there.

23. But let’s think bigger. In JUST this picture taken by the Hubble telescope, there are thousands and thousands of galaxies, each containing millions of stars, each with their own planets.

Via hubblesite.org

24. Here’s one of the galaxies pictured, UDF 423. This galaxy is 10 BILLION light years away. When you look at this picture, you are looking billions of years into the past.

Via wikisky.org

Some of the other galaxies are thought to have formed only a few hundred million years AFTER the Big Bang.

25. And just keep this in mind — that’s a picture of a very small, small part of the universe. It’s just an insignificant fraction of the night sky.

26. And, you know, it’s pretty safe to assume that there are some black holes out there. Here’s the size of a black hole compared with Earth’s orbit, just to terrify you:
