The Heaven's Declare — Part 3

Continuing the series, and moving farther out from a few stunning facts about our earth and sun, the next part I shared about in my teaching (and the handout I later made that I am taking these from) is about our Solar System. Next post, our Milky Way galaxy. After that, our universe. 
   As with all these posts, I can't verify the facts, but I've tried to get them from web sites that seem to know what they are talking about (whatever that exactly means). Enjoy. Reflect. And be in awe. We have a mighty and awesome God, and the Heavens declare His glory. Don't forget the "God Thought" at the end of each post . . . He, and your faith and relationship with Him, is truly what this is all about, not just getting puffed up with some more knowledge. May He pour out revelation and a deep awareness of His love for you and His presence as you read this.   —Erick

Our Solar System
How big is the network of our sun and the planets orbiting it? Let’s use an example someone made up of a walk. Imagine each 3' step you take to represent 1,000,000 miles (yes, one million miles). Picture a football field and start at the back of one of the end zones and pretend you are where the sun is. Now walk forward, cross the end zone, past the 50 yard line, and continue in to your opponent’s side of the field. When you get to their 17 yard line you have reached the earth (remember, each step was 1 million miles!). Now, continue walking over 1.5 miles and you will get to Neptune, the farthest out planet if you don’t want to count poor Pluto (if you do you’ll need to walk over 2 miles from the back of the end zone where you started). The same site said that if you got on a jet and flew at 600 miles per hour from the Sun to Neptune, it would take 513 years. If you could drive the same distance, it would take 4,400 years.

Defining a Few Terms
Since we are starting from here out to get into some terms that represent some big numbers, here's a few simplified definitions and way of looking at things to help us try and grasp them.


Light Year: How far you would travel in one year if you traveled constantly at the speed of light, which is about 186,000 miles per second (or, around the world at the equator over seven times in a second).

Billion: If you typed the letter “a” on a sheet of paper 1,000 times, you’d need 1 million sheets to have a billion letter “a”s. Or, if you started counting now, it would take you 32 years to count a billion seconds.

Astronomical: We use this term to describe things really, really BIG! No wonder. It comes from the root “astro” pertaining to stars and celestial bodies.

God Thought: Ephesians 1:4 says that “. . . He chose us in Him before the foundation of the world”—before He created one bit of this He already knew you, loved you, and had a plan to restore you to Him through Jesus’ death. You are truly precious! In fact, His entire creation of the universe was the opening act to His culmination . . . creating us!

The Heaven's Declare — Part 2

Here's the part of my handout dealing with our "local" space—Earth and our sun. In Part 3 we'll look at our solar system, and in posts after that our galaxy and then the universe. At the end of each will be a "God Thought". I encourage you to read and meditate on them. After all, knowledge for the sake of knowledge simply puffs us up and makes us arrogant—we then become people who spout all the right words and arguments, but have nothing of the love, humility, and gentle service of Christ. And, without love, we have nothing. The point of this knowledge is to glorify God, strengthen our faith, and equip us for the work of ministry. May God bless you as your read these. (Note: Please remember the statement in Part 1 that, though I state these things as fact, I obviously can't personally verify them through observation or my own measurement, and I can't even tell you where on the internet I got them all. Not to mention that the numbers probably change with every new discovery or better telescope. I can say I tried hard to use facts I found in multiple places, and to not exaggerate anything to make a point.)

Earth—one of eight (or nine?) planets orbiting our sun, making up our solar system. Mostly covered in water, it is almost 25,000 miles around at the equator. It rotates on its axis fully once per day, which means we are spinning at over 1,000 miles per hour at the equator. At the same time we are spinning at over 1,000 miles per hour, we are orbiting the sun (which is 93 million miles away from us) at almost 67,000 miles per hour, all on this shell of rock and land and water that contains inside it a core with temperatures estimated between 7,000–12,000°F (to compare, water boils at 212°F, and human skin is supposedly not comfortable above 140°F). And yet, we can balance on a balance beam, sip coffee without spilling, play catch, experience sun and snow, and sleep peacefully.

Our Sun—our nearest star, has a diameter 109 times bigger than the earth’s. We could fit 1.3 million earths inside our sun. The sun makes up 99.8% of the mass in our solar system, with Jupiter and Saturn taking up most of the other .2% (the earth really doesn’t even register on the scale). The center of the Sun is approximately 27,000,030°F, and the surface of the Sun is about 9,932°F.
    And yet, our sun is rather tiny in comparison to other stars out there. For example, Canis Majoris, the largest known star in volume (not mass) has a radius that is estimated to be 1,800–2,100 times larger than our sun’s radius, and to be around 500,000 times brighter than our sun. One site said that if you were to make a model, with our earth a sphere of a diameter of .39 inches (less than half an inch), then, to represent Canis Majoris you’d need a sphere with a diameter of 1.43 miles! And, R136A1, the largest know star by mass (not volume), is estimated to have surface temperatures exceeding 72,000°F—seven times hotter than our sun’s surface temperature!

God Thought: Psalm 33:6 says, “By the word of the Lord the heavens were made, and by the breath of his mouth all their host.” If these stars were brought forth by the word of the Lord and the breath of His mouth, what is going on in your life that is too big for you to trust Him with it?
