Title: Astronomy Question Post by: Hobgoblin32 on Mar 24, 2013 If the distance between the Sun and Earth is 150,000,000km and the Sun has a diameter of about 1,400,000 km, determine a scale factor in terms of km/solar diameter, and then determine the Earth-Sun distance in terms of solar diameters.
Title: Re: Astronomy Question Post by: bio_man on Mar 24, 2013 1 solar diameter is 6.96 x 10^8 meters.
Therefore: 1st: 150,000,000 convert to meters by multiplying by 1000: 150,000,000,000... 2nd: Set up a ratio: 1 solar diameter = 6.96 x 10^8 m .........x............ = 150,000,000,000 Cross multiply: 150,000,000,000 / 6.96 x 10^8 m = 215.517. Hope that helps. Title: Re: Astronomy Question Post by: Hobgoblin32 on Mar 24, 2013 Thanks! There's also a second part to this that I forgot to post. when you get this scale factor measure how many suns will fit between the position of the sun and jupiter (assuming that the distance between the sun and Jupiter is 5.2 AU and the suns diameter is still 1,400,000 km.) What would I do in this case? very lost.

Title: Re: Astronomy Question Post by: Hobgoblin32 on Mar 24, 2013 Thank you! But one last question. I'm confused as to how the 215.517 relates to the 2nd part of the question (sun-jupiter part). Was 215.517 the final answer for the first question?
Title: Re: Astronomy Question Post by: bio_man on Mar 24, 2013 and then determine the Earth-Sun distance in terms of solar diameters. Yes, that first post related to this ^^ Sorry about the confusion. |
