Hello!

I can't understand the following paragraph fully. Help me, please!

...............................................................................................................

If two astronomers observe a planet at the same time, they can measure the angles indicated as A and B and measure the distance between the telescopes. This give them enough information to be able to calculate the distance to another planet. The greater the distance is between them, the more accurate their calculations can be.

..................................................................................................................

They can calculate the distance E1 E2 and the angles <S1 E1 E2 and <S1 E2 E1.

And then, they can calculate the distance E S1. So, I thought, from the contaxt, the another planet should be S1. But, It sounds like referring to another planet S2. What do you think? Is the another plannet the first star from the earth or any other star?

I can't understand the following paragraph fully. Help me, please!

I'll use some symbols.( E for the earth, E1, E2 for the spots of two astronomers, S1 for a planet, S2 for another planet, S3 ...for another planet and so on..)__What is the another planet?__They can calculate the distance E1 E2 and the angles <S1 E1 E2 and <S1 E2 E1.

I think the intention is that they can calculate the distance to the planet they are looking at. In other words, only one planet is involved. The term 'to another planet' seems misleading to me. I Think the author should have said 'to

Is the another plannet the first star from the earth or any other star? First, note that a planet is not a star. They are different. eg The Earth and Mars are planets. The sun is a star.

I believe the idea is that method described can be used for any planet that can be observded from Earth, and not just the closest one.

Best wishes, Clive
