Até agora já foram descobertos mais de 70 Diretor Editor Chefe mil asteróides, a maior parte situados no cinturão de asteróides entre as órbitas Hemerson Brandão de Marte e Júpiter. [email protected] Além desse cinturão podemos encontrar pequenos grupos de asteróides isolados chamados de Troianos que compartilham a mesma órbita de Júpiter. Existem Editora Científica também aqueles que possuem órbitas livres, como é o caso de Hidalgo, Apolo e Walkiria Schulz Ícaro.

A maior cratera visível de nosso planeta é a Meteor Crater, com cerca de 1 km de Diagramadores diâmetro e 600 metros de profundidade. -
ASTR 1010 Homework Solutions
ASTR 1010 Homework Solutions Chapter 1 24. Set up a proportion, but be sure that you express all the distances in the same units (e.g., centimeters). The diameter of the Sun is to the size of a basketball as the distance to Proxima Centauri (4.2 LY) is to the unknown distance (X), so (1.4 × 1011 cm) / (30 cm) = (4.2 LY)(9.46 × 1017 cm/LY) / (X) Rearranging terms, we get X = (4.2 LY)(9.46 × 1017 cm/LY)(30 cm) / (1.4 × 1011 cm) = 8.51 × 108 cm = 8.51 × 103 km = 8510 km In other words, if the Sun were the size of a 30-cm diameter ball, the nearest star would be 8510 km away, which is roughly the distance from Los Angeles to Tokyo. 27. The Sun’s hydrogen mass is (3/4) × (1.99 × 1030 kg) = 1.49 × 1030 kg. Now divide the Sun’s hydrogen mass by the mass of one hydrogen atom to get the number of hydrogen atoms contained in the Sun: (1.49 × 1030 kg) / (1.67 × 10-27 kg/atom) = 8.92 × 1056 atoms. 8 11 29. The distance from the Sun to the Earth is 1 AU = 1.496 × 10 km = 1.496 × 10 m. The light-travel time is the distance, 1 AU, divided by the speed of light, i.e., 11 8 3 time = distance/speed = (1.496 × 10 m) / (3.00 × 10 m/s) = 0.499 × 10 s = 499 s = 8.3 minutes. 34. Since you are given diameter (D = 2.6 cm) and angle, and asked to find distance, you need to rewrite the small-angle formula as d = (206,265)(D) / (α). -

Meteor Activity Outlook for July 11-17, 2020
Meteor Activity Outlook for July 11-17, 2020 Wade Earle captured this fireball while photographing noctilucent clouds from eastern Oregon on June 23, 2020 © Wade Earle During this period, the moon reaches its last quarter phase on Monday July 13th. At this time, the moon is located 90 degrees west of the sun and rises near 0100 local daylight saving time (LDST). As the week progresses the waning crescent moon rises later in the morning with each passing night. This allows the window of dark skies to increase as the week progresses. The most active hours just prior to dawn will have slight interference from moonlight but one can overcome this simply facing in a direction where the moon is not visible within your field of view. The estimated total hourly meteor rates for evening observers this week is near 3 for those viewing from the southern hemisphere and 2 for those located north of the equator. For morning observers, the estimated total hourly rates should be near 13 as seen from tropical southern locations (25S) and 14 as seen from mid-northern latitudes (45N). The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness, and experience in watching meteor activity. Morning rates are reduced during this period due to moonlight. Note that the hourly rates listed below are estimates as viewed from dark sky sites away from urban light sources. Observers viewing from urban areas will see less activity as only the brighter meteors will be visible from such locations. -
Constellations
Your Guide to the CONSTELLATIONS INSTRUCTOR'S HANDBOOK Lowell L. Koontz 2002 ii Preface We Earthlings are far more aware of the surroundings at our feet than we are in the heavens above. The study of observational astronomy and locating someone who has expertise in this field has become a rare find. The ancient civilizations had a keen interest in their skies and used the heavens as a navigational tool and as a form of entertainment associating mythology and stories about the constellations. Constellations were derived from mankind's attempt to bring order to the chaos of stars above them. They also realized the celestial objects of the night sky were beyond the control of mankind and associated the heavens with religion. Observational astronomy and familiarity with the night sky today is limited for the following reasons: • Many people live in cities and metropolitan areas have become so well illuminated that light pollution has become a real problem in observing the night sky. • Typical city lighting prevents one from seeing stars that are of fourth, fifth, sixth magnitude thus only a couple hundred stars will be seen. • Under dark skies this number may be as high as 2,500 stars and many of these dim stars helped form the patterns of the constellations. • Light pollution is accountable for reducing the appeal of the night sky and loss of interest by many young people as the night sky is seldom seen in its full splendor. • People spend less time outside than in the past, particularly at night. • Our culture has developed such a profusion of electronic devices that we find less time to do other endeavors in the great outdoors. -
Armchair Treasure Hunt 2017 Answers from the Pathfinders
Armchair Treasure Hunt 2017 Answers from the Pathfinders Hunt themes and approach The hunt PDF document is entitled '7,4,4' - a crossword-style clue for 'Another fine mess' *. This is a first clue to the theme of the hunt: Mess. Or rather the themes of the hunt, which are all based around words/names beginning with Mess. The five most obvious are clued by the ATH Scoreboard i.e. Olivier Messiaen Lionel Messi Mr Messy The battle of Messines Charles Messier The River Mess in Luxembourg also plays an important role, and there are other less prominent Mess connections, including Messalina (with her connections to Roman Britain and the treasure location), Messerschmitt and Messel. All of this points to the treasure location in Messing, Essex. Both literally, and also through the need to fix mess in order to find it. The (Mr.) Messy theme yields nothing of real use; we can only locate the box by sorting out this mess using the other main themes. (* At a stretch, Oliver Hardy’s “Another fine mess” might also be a link to Olivier Messiaen) The route to the box The Mess theme and other clues (such as Inworth village sign, the Messing coat-of-arms armorial leftovers, and the re-translated Blechbläser), hint at the village of Messing in Essex, as the treasure location. This is confirmed by the “Night Sky” solution which begins: FIND AN ESSEX PLACE AMID EVERY EIGHTH BOX IN SYRIA This is MESSING (found from every 8th hexagon in Messi’s Syrian journey.) The directions continue: GO W FROM CH TURN L From Messing Church, go west along Kelvedon Road and turn left down School Road. -
