  • It’s almost impossible to imagine the vast distances at play when picturing the size of our solar system,

    當我們在想像太陽系有多大時,其實我們根本沒辦法去想像那些距離究竟有多遠。

  • and especially the distances to the neighbouring stars.

  • objects and distances like buildings, city blocks and

    相當有概念,像是建築物,城市街區

  • even entire cities, but when someone says that Pluto

    甚至整個城市的大小。但當有人跟你說

  • is 7.3 BILLION kilometers away, what does that really look like?

    冥王星距離我們73億公里時,這又是怎麼樣的距離呢?

  • In order to get a sense of the immense scale of our

    以及行星間彼此的距離有個概念

  • let’s build a scale model in a city so we have some

    讓我們在城市裡建構一個模型

  • common reference points for judging the relative distances.

    這樣我們可以有一些共同參考點來判斷這些相對距離

  • Well start in an American football field with the sun

    一開始,我們將太陽擺在一個美式足球場的50碼線上

  • placed at the 50 yard line and scaled to the size of a 44cm beach ball.

    並且將其縮小如一顆直徑44公分的海灘球一般

  • At this scale, Earth and Venus are the size of a small

    在這比例上,地球跟金星的大小就如同

  • stud earring, only 4mm in diameter. Jupiter is about

  • Now let’s put them in their proper locations based on

    現在,讓我們根據遠日點,或是說距離太陽最遠的距離

  • their aphelions, or their farthest distances from the sun.

    將他們放在適當的位置

  • Well find Mercury near the 26 yard line or 22 meters

    我們將會發現水星約是位於26碼線附近或是距離太陽22公尺遠

  • from the sun. That’s equal to about 70 million kilometers at actual scale.

    這在實際距離上等同於7000萬公里

  • Venus will be near the 12 yard line,

  • 34 meters from the sun.

    距離太陽34公尺遠

  • Earth can be found inside the end zone at 48 meters

    地球則會位於球門區內

  • And our little candy sprinkle-sized Moon is about 13cm

    至於我們如糖果碎班,小小的月球

  • from the earring-sized Earth.

    距離耳釘般大小的地球則約是13公分遠

  • To find Mars, well have to get up to the middle of

    要找到火星的話,我們必須爬到底層觀眾席的中間

    在這比例下,火星直徑約是2公厘

  • can see compared to this bottle cap.

    你可以用這個瓶蓋來比較大小

  • After Mars, the distances start to increase rapidly.

    過了火星之後,各行星彼此間的距離開始急遽增加

  • To get to Jupiter, well have to head out 260m or 850ft,
