Sediment records have confirmed that Jupiter and Venus change Earth's orbit from virtually circular to noticeably elliptical and back every 405,000 years. Christopher Intagliata reports.

I am proud to see ESA leading the first ever mission to return from Mars. As part of our strong cooperation with NASA, we are working to return pristine material from Mars – scientific treasure that the world’s scientists will study for generations to come and help ...

Although Trojan asteroids have been known for decades in other Solar System planets2such as Venus3, Mars4, Jupiter5, Uranus6, and Neptune7, it wasn’t until 2011 that asteroid 2010 TK7was found to be the first (and hitherto unique) Earth Trojan (ET) asteroid8. ET asteroids have been ...

the other planets in its solar system. As a result, these other planets have only a weak effect on its orbit and movement. So, Kepler-186f generallyhas a fixed obliquity, similar to Earth. Even without a large moon, it doesn’t have wildly changing or unpredictable seasons like Mars. ...
Others track the planet’s progression along its orbit around the Sun (year-based). Jupiter Breaks the Calendar If this got you worried about the calendrical complications facing future Mars settlers, you might find some consolation in the fact thatno one will ever settle on Jupiter. ...
