• 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.

尤其是地球到鄰近星球的距離

• Our brains are quite good at dealing with medium-sized

我們的大腦對於中型的物體以及其距離

• 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

為了讓大家對太陽系的巨大

• solar system and the distances between the planets,

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

一個小小的耳釘，僅僅直徑4公厘

• the size of a golf ball, Uranus and Neptune are the

木星的大小如同一顆高爾夫球，天王星和海王星

• size of a small marble, and our moon and Pluto are

的大小如同一顆小彈珠，我們的月亮和冥王星

• closer to the size of a round candy sprinkle,

則接近圓形糖果碎屑的大小

• only 1mm in diameter.

直徑只有1公厘

• 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,

金星大約在12碼線附近

• 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

• from our beach ball sun.

距離沙灘球般大小的太陽48公尺遠

• 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

• the lower seating section, about 80m from the sun.

這距離約是離太陽80公尺

• At this scale, Mars is about 2mm in diameter, as you

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,

要到木星，我們必須再往外走260公尺或是850呎

• which is halfway into the parking lot.

這已經是在通往停車場的半路上了

• Saturn will take us all the way through the parking

要到達土星，則要一路穿越停車場

• lot and to the edge of the first block of the city,

一直走到這個城市的第一個街口，

• or 480m from the sun.

換句話說，就是距離太陽480公尺遠。

• Uranus is over 5 city blocks past the parking lot.

天王星則在距停車場五個街口外

• That’s 950 meters from the centre of the stadium.

這距離足球場中央已經是950公尺了

• Our small marble-sized Neptune takes us right to the

我們如同彈珠般大小的海王星則

• edge of our model city, almost 10 blocks from the

要讓我們走到市中心的邊緣，大約距停車場10個街口

• parking lot and 1.43km, or 0.89 miles from the sun.

距離太陽約1.43公里，或是0.89英哩

• Now well make our way to little dwarf planet Pluto,

現在，我們將啟程走到矮行星，冥王星

• nearly 10 football fields past Neptune.

經過海王星再走約10個足球場的距離

• Fun fact: In this part of the animation, were

告訴你們一個有趣的事實: 在這部分動畫中

• currently travelling at a scale speed of nearly 600 times the speed of light!

我們的旅行是用接近600倍光速的速度來前進

• Pluto, here less than 1mm in diameter, is well beyond

冥王星，在這比例下其直徑小於1公厘

• the city and across the bridge at over 2.3 km, or 1.4 miles from the centre of the stadium.

位置已超出市中心很遠，甚至過了座橋，其距離場館中央已超過2.3公里，或是1.4英哩

• That’s what 7.3 billion km looks like when our entire planet is scaled down to a mere 4mm.

這就是當我們把星球縮小到僅僅四公厘時，730億公里看起來會是這個樣子。

• Now how far away do you think the nearest STAR would

你認為，在這個比例之下，離我們最近的恆星

• be at this scale?

有多遠呢？

• If our beach ball sun was in Yankee Stadium in New

假如沙灘球般大小的太陽位於紐約的洋基球場

• York City, our entire solar system would be contained

那麼整個太陽系的大小會涵蓋

• within a 2 to 3 km radius between Harlem and the Bronx.

半徑2到3公里的地區，也就是哈林區到布朗克斯的範圍

• At this scale, here is where Proxima Centauri, the

在這個比例之下，這就是Proxima Centauri

• nearest star to our sun, would be found.

這顆離太陽最近的行星，會被找到的位置。

• Not yet

還沒到

• Even farther!

還得更遠！

• The nearest star would be past Mumbai India at about

要找到離太陽最近的恆星，得經過印度孟買

• 12,690 km away!

大約12,690公里遠！

• If we ever want to explore the neighbouring star

假如我們想到鄰近的恆星星系去探險

• systems, I think were going to need some faster ships!

那我想我們需要一些更快的太空船！

• Now that youve got a sense for the scale of our solar
