Pluto has been hard to measure from Earth because of the atmosphere. In 2007 Young and Buie measured Pluto as having a diameter of 2322 km. In 2015 the New Horizons probe reached pluto and measured it up close and we now know the actual diameter is 2372 km. What was the percent error of the 2007 measurement? Enter your answer as a percent with a negative value if the 2007 measurement was too small and a positive value if it was too large.
The iron meteorite that created Barringer Crater (Arizona) was 50 m in diameter. It caused a crater 1.2 km (1200 m) in diameter, that is, 24 times bigger than the impactor. Keeping in mind that the size of the crater depends on many factors, such as the type of rocks present in the area, estimate the approximate size of the impactor that produced Mare Serenitatis.
A sample from a meteorite that landed on Earth has been analyzed, and the result shows that out of every 1,000 nuclei of potassium-40 originally in the meteorite, only 250 are still present, meaning they have not yet decayed. How old is the meteorite (in yr)? (Hint: See the figure below.) (Note: The half-life of potassium-40 is 1.3 billion years.) Figure A graph and a series of bar charts above it both show the percentage of radioactive atoms remaining in a mineral sample. Detailed descriptions of the graph and the bar charts are available in the adjacent lists.
Tutorial You observe a comet 0.32 AU from Earth with a tail that is 1.7 degrees long. How long is the tail in AU? How long is the tail in kilometers? How many times could the U.S. fit along the length of the tail? (The width of the U.S. is 4,313 km.) Part 1 of 3 You observe a comet 0.32 AU from Earth with a tail that is 1.7 degrees long. How long is the tail in AU? We use the small angle formula to calculate the length of the tail in AU. arc seconds d Ꮎ 2.06 x 105 D Solving for the linear distance gives: dAU = DAU dAU = = AU arc seconds 2.06 x 105
How would the solar system be different if the solar nebula had cooled, with a temperature half its actual value? [select all that apply] options: There would be more comets. Life would have been very unlikely to evolve here. There would be no comets. There would be fewer asteroids. There would be more asteroids. Jovian planets would have formed closer to Sun.
