Planet Infomation on Friday, July 30, 2010 for TUCSON 

MERCURY  Mercury still can be seen during the first week of June but is getting lower in the sky each day. The small planet rises 30 minutes before sunrise so a very clear eastern horizon is needed to spot it. After that the planet dives down to reach superior conjunction with the sun at the end of June
 
Constellation Leo    RA Position 10 hr 18 min
Distance from Sun 42,283,852 Miles    Dec Position 10° 21'
Distance from Earth 91,595,433 Miles    Magnitude 0
Light Travel Time 0 hr 8 min    Rise Time 7:41 AM
Phase 58%    Transit Time 2:11 PM
Angular Size 6.84 sec of arc    Set Time 8:36 PM
VENUS  Venus can be easily spotted in the evening sky this month as it blazes away at a magnitude of -4.1. Venus is still small as seen though a telescope and is at a 80 percent phase and still fairly small in size. During the summer, Venus will grow larger and brighter as the sister planet gets closer to earth. On June 19 and 20, the sister planet passes nearby the famous open star cluster Messier 44 otherwise know as the Beehive cluster.
 
Constellation Leo    RA Position 11 hr 28 min
Distance from Sun 67,489,333 Miles    Dec Position 3° 39'
Distance from Earth 79,272,915 Miles    Magnitude -5
Light Travel Time 0 hr 7 min    Rise Time 9:08 AM
Phase 59%    Transit Time 3:21 PM
Angular Size 19.85 sec of arc    Set Time 9:30 PM
MARS  Mars is located in the constellation of Leo where it passes near by the bright star Regulus June 6th where it will be only one degree from the bright star. Now at 155 million miles, you will need a large telescope and good seeing to bring out any details on the surface. The planetary disk size is only 6 seconds or arc so even with large telescopes, observing days for Mars are coming to an end soon

 

Constellation Virgo    RA Position 12 hr 0 min
Distance from Sun 148,588,408 Miles    Dec Position 0° 26'
Distance from Earth 185,200,944 Miles    Magnitude 1
Light Travel Time 0 hr 16 min    Rise Time 9:48 AM
Phase 93%    Transit Time 3:53 PM
Angular Size 4.70 sec of arc    Set Time 9:53 PM
JUPITER  Jupiter rises as Saturn sets in the early morning hours just after midnight. By 3am local time the large planet is high enough in the sky to make some good observations. Jupiter moves around Uranus in June with the closest approach around June 6th. During that time, a wide field eyepiece can capture both planets in the same field of view. Any size telescope can make out the 4 moons and some of the surface features. With a larger telescope you start picking out the fine details on the surface.

 

Constellation Pices    RA Position 0 hr 14 min
Distance from Sun 461,821,112 Miles    Dec Position 0° 1'
Distance from Earth 403,170,069 Miles    Magnitude -3
Light Travel Time 0 hr 36 min    Rise Time 10:00 PM
Phase 99%    Transit Time 4:09 AM
Angular Size 45.38 sec of arc    Set Time 10:08 AM
SATURN  Saturn is still in great viewing position and is visible until about midnight when it has set. Still in the constellation of Virgo and since the ring system is still very thin; only 1 degrees line of slight, the small moons can easily be seen in just about any size telescope. Larger telescope can use the advantage of the planets thin rings to view some of the surface features on the planet.
 
Constellation Virgo    RA Position 12 hr 6 min
Distance from Sun 887,887,913 Miles    Dec Position 1° 46'
Distance from Earth 940,006,542 Miles    Magnitude 1
Light Travel Time 1 hr 24 min    Rise Time 9:50 AM
Phase 100%    Transit Time 3:58 PM
Angular Size 16.38 sec of arc    Set Time 10:02 PM
URANUS  Uranus rises after midnight with Jupiter as the two appear quite close together in June. In the constellation of Aquarius you will need a star chart to look for the distant world. Jupiter will help you find the planet.
 
Constellation Pices    RA Position 0 hr 3 min
Distance from Sun 1,869,636,323 Miles    Dec Position 0° 30'
Distance from Earth 1,813,334,928 Miles    Magnitude 6
Light Travel Time 2 hr 42 min    Rise Time 9:50 PM
Phase 100%    Transit Time 3:57 AM
Angular Size 3.37 sec of arc    Set Time 9:55 AM
NEPTUNE  Neptune rises around midnight local time. Large telescopes can make out the planetary disk but don’t expect to see any detail. The distant planet is now in the constellation with its twin planet Uranus.
 
Constellation Aquarius    RA Position 22 hr 0 min
Distance from Sun 2,796,402,136 Miles    Dec Position -12° 40'
Distance from Earth 2,707,794,099 Miles    Magnitude 8
Light Travel Time 4 hr 2 min    Rise Time 8:19 PM
Phase 100%    Transit Time 1:51 AM
Angular Size 2.14 sec of arc    Set Time 7:22 AM
PLUTO  Pluto is at opposition this month and visible all night long. The best time to hunt for the small world is around midnight when it is highest in the sky. You will need a large telescope and a good sky chart just to even see the tiny dwarf planet. If you have a DSLR camera or a CCD, you can capture the planet in only a few seconds. By repeating this the next few nights, you can create an animation that shows Pluto drifting against the background stars.
 
Constellation Sagittarius    RA Position 18 hr 10 min
Distance from Sun 3,055,180,554 Miles    Dec Position -18° 11'
Distance from Earth 2,921,572,358 Miles    Magnitude 14
Light Travel Time 4 hr 21 min    Rise Time 4:44 PM
Phase 100%    Transit Time 10:01 PM
Angular Size 0.26 sec of arc    Set Time 3:17 AM
