Illustration of the solar system, showing the paths of the eight major planets as they orbit the ... [+] Sun, plus the asteroids and comets. The four inner planets are, from inner to outer, Mercury, Venus, Earth and Mars. The four outer planets are, inner to outer, Jupiter, Saturn, Uranus and Neptune.
That depends on when you look—and how late at night you look—but as this summer gathers pace, the planets are going to become brighter and much more convenient to see.
Giant Jupiter, with its 79 moons, is king of the planets - KTAR.com
Did you know that Jupiter has some two and a half times the mass of all the other planets in the solar system? With a diameter of some 88,000 miles, Jupiter is a gas giant that dwarfs Earth.
We are lucky to have a planet such as Jupiter in the solar system, as it performs a major task by clearing the solar system of many unwanted asteroids and comets, which might be headed towards Earth.
Jupiter has 79 known moons — the most of any planet in the solar system — and more are expected to be discovered by the Juno spacecraft.
Most planets on tilted orbits pass over the poles of their suns | Science News
Earth is on an orderly path around the sun, orbiting in nearly the same plane as our star's equator. In 2008, however, astronomers began finding worlds in other solar systems that sail far above and below their star's equatorial plane.
Now a surprising discovery about these wrong-way worlds may eventually reveal their origin: Most of them follow polar orbits ( SN: 6/17/16 ). If Earth had such an orbit, every year we'd pass over the sun's north pole, dive through its equatorial plane, then pass below the sun's south pole before coming back up again.
Out of This World Discovery by Citizen Scientists: Two Gaseous Planets Around a Bright Sun-Like

At night, seven-year-old Miguel likes talking to his father Cesar Rubio about planets and stars. "I try to nurture that," says Rubio, a machinist in Pomona, California, who makes parts for mining and power generation equipment.
Plants among the planets: Research from 2 N.C.
A SpaceX Falcon 9 rocket with a Dragon 2 spacecraft lifts off June 3 at the Kennedy Space Center in Cape Canaveral, Fla. The rocket's resupply mission to the International Space Station included carting some 7,300 pounds of science, research and hardware. Plant projects from two N.C. State University professors was among the research sent to the space station.
The biology projects of two N.C. State University professors are now aboard the International Space Station and may soon help provide answers about how plants respond to extreme environments.
Babies In Space: The Challenges Of Colonizing Other Planets | KJZZ
Another space race is in full swing as private space travel firms are competing with Russia, China and the United States to push the envelopes of exploration on Mars and the moon.
China and Russia are participating in a joint program to establish a permanent base on the moon within 25 years, and Elon Musk's Space X has proposed building a colony on Mars by 2050.
Many of these plans involve long-term travel and permanent colonization, and the sustainability of a human presence in space will eventually result in a need to procreate. But doing this in space poses many challenges — politically, ethically and medically. And being born somewhere other than Earth raises citizenship questions, too.
