24 CHAPTER 1: OUR PLACE IN THE UNIVERSE

25 What is our place in the universe Our cosmic address

26 Scale of the Universe The numbers in astronomy are so large, and small, that astronomers use scientific notation 10 0 = = = = x 10 3 = = 10, x 10 4 = 74,000 For small numbers 10-1 = = x 10-2 = = x 10-3 =

27 Scale of the Universe Astronomical distances and sizes are very, very large. So astronomers use different units Astronomical Unit (AU) Average distance between the Sun and the Earth 93,000,000 miles 150,000,000 km = 1.5 x 10 8 km Light Year (LY) Distance light travels in one year 9.46 x km 63,000 AU = 6.3 x 10 4 AU parsecs (pc)

28 The Scale of the Solar System On a 1 to 10 billion scale The sun is the size of a large grapefruit Earth is the size of the tip of a ball point pen, 15 meters away Where would the nearest star to the Sun (Alpha Centauri another grapefruit) be?

29 How big is the universe The universe in powers of 10:

30 How big is the Milky Way Galaxy? The Milky Way has about 100 billion stars On the same 10 billion to 1 scale

31 How big is the universe? The Milky Way is one of about 100 billion galaxies in the observable universe stars per galaxy x galaxies = stars It has as many stars as grains of (dry) sand on all of Earth s beaches

32 At the scale of the size of a planet or moon we describe things in terms of kilometers (km)

33 At the scale of the Solar System distances are described in terms of the Astronomical Unit or AU (average distance from Earth to the Sun).

34 At the scale of the Milky Way Galaxy distances are described in terms of Light-years which is the distance light travels in one year.

35 Thousands of km Astronomical Unit A few to about 1,000 Light-years 10,000 to 100,000 Light-years Millions of Light-years Billions of Light-years

36 How do human lifetimes compare to the age of the universe? The Cosmic Calendar Compress the history of the universe into 1 year
