Orbit and Mass
The planet's orbit has a low eccentricity, like most of the planets in our solar system. The semimajor axis of the orbit is only 0.63 AU, similar to that of Venus. However, HD 69830 is a less massive and energetic star than the Sun, thereby putting the planet within its habitable zone. It is 17 times the mass of the Earth, and 42 light years away from the solar system, and has a close to circular orbit.

Famous quotes containing the words orbit and, orbit and/or mass:
“Words can have no single fixed meaning. Like wayward electrons, they can spin away from their initial orbit and enter a wider magnetic field. No one owns them or has a proprietary right to dictate how they will be used.”
—David Lehman (b. 1948)
“The human spirit is itself the most wonderful fairy tale that can possibly be. What a magnificent world lies enclosed within our bosoms! No solar orbit hems it in, the inexhaustible wealth of the total visible creation is outweighed by its riches!”
—E.T.A.W. (Ernst Theodor Amadeus Wilhelm)
“The mass believes that it has the right to impose and to give force of law to notions born in the café.”
—José Ortega Y Gasset (1883–1955)
