What object is the same size as Earth?

Venus and Earth are about the same size, Earth being slightly larger. Mars and Mercury are much smaller than Earth and the other planets are much larger.
Why did Oumuamua speed up?
After ruling out effects from “solar-radiation pressure, drag- and friction-like forces, interaction with solar wind for a highly magnetized object, and geometric effects” due to the shape of the asteroid, they concluded that Oumuamua accelerated due to “comet-like outgassing.” This means that Oumuamua vents gases when …
Can we see Voyager 1 with telescope?
These radio telescopes cannot see Voyager 1 in visible light, but rather “see” the spacecraft signal in radio light. Antennas make up a radio telescope like mirrors and pixels make up an optical one. The telescopes made a special attempt to look for Voyager 1’s signal to test their sensitivity.

Which object represents the sun?
The astronomical symbol for the Sun is a shield with a circle inside. Some believe this inner circle, or “boss” represents a central sun spot. The symbol for Mercury represents the head and winged cap of Mercury, god of commerce and communication, surmounting his caduceus (staff).
Is the sun the largest object in the solar system?
The Sun is the largest object in our solar system. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it.
What is an interstellar visitor?
Interstellar visitors in the Solar System cover the whole range of sizes – from kilometer large objects down to submicron particles. Also, interstellar dust and meteoroids carry with them valuable information from their parent systems. Detection of these objects along the continuum of sizes is, however, not evident.
Where is Oumuamua located?
Today Oumuamua, the Hawaiian term for “scout,” as the object was named, is now long gone, somewhere between the orbits of Saturn and Neptune and on its way to the Great Out There, but astronomers are still wondering and debating what it was.
